					Self-direction + Collaboration Self-direction + Collaboration Please join CGA members and Kristy Tiampo for our third Hidden Curriculum seminar in the series to discuss self-direction and collaboration! The Hidden Curriculum seminars were developed by Amanda Donaldson, Galen Gorski, Colleen Murphy, Jenny Pensky, Adam Price, Christina Richardson, Araceli Serrano, and Margaret Zimmer* because much of the graduate school experience is focused on tangible and formal skill development surrounding research and teaching. These seminars focus on the informal “hidden curriculum”/"soft skills" in graduate school that can complement formal student learning to help individuals lead successful research careers. The third seminar of this series will focus on self-direction and collaboration, led by Kristy Tiampo from the CU Graduate School. Dr. Tiampo is a Professor and the Director of Geography at CU Boulder. This event has passed but below you can find the recording of the seminar, the slides, and additional readings. Please reach out of you have any more questions. * Source: Zimmer, M., A. Donaldson, G. Gorski, C. Murphy, J. Pensky, A. Price, C. Richardson, A. Serrano (2021).

Millions of tons of these chemicals are produced every year, with an estimated 30 kilotons of decamethylcyclopentasiloxane (D5) emitted into the environment every year, with additional contributions from other VMS. A large source of VMS to the environment is from use of personal care products containing these compounds. Due to environmental concerns about the impact of these compounds, the European Union placed restrictions on the quantity of VMS in wash-off personal care products in 2018 with recommendations to increase the restrictions to include some industrial processes in 2021. Although there is significant interest in these high-production chemicals, the understanding of the environmental fate of these compounds is incomplete. It is predicted that >90% of VMS released to the environment will partition into the atmosphere. Once these compounds are in the atmosphere, they can react with hydroxyl radicals (OH) or chlorine atoms (Cl) through hydrogen-abstraction reactions, though the previously reported rate constants for reactions with OH vary by more than a factor of 3 and only one measurement exists for the rate constant with Cl atoms. Additionally, previously published works reported inconsistent oxidation products of these compounds, likely due to unconstrained oxidation chemistry in their experiments. To better constrain the atmospheric chemistry and fate of these compounds, I measured the kinetics of seven VMS with OH radicals and Cl atoms in a 1 cubic meter FEP Teflon™ chamber I designed and built. Additionally, I measured the oxidation products of VMS in a variety of atmospheric conditions to better constrain the oxidation mechanism. Finally, I used quantum theoretical calculations to investigate the plausibility of the reactions proposed from our experimental results."

	Atmospheric Chemistry Program Seminar Atmospheric Chemistry Program Seminar Kinetics of Oligomer-Forming Reactions Involving the Major Functional Groups Present in Atmospheric Secondary Organic Aerosol Particles Hannah Maben, ANYL Master's Thesis Defense, Ziemann group "Atmospheric organic aerosol particles impact climate as well as human and environmental health. Secondary organic aerosol (SOA), which is formed by the gas-to-particle partitioning of products of the oxidation of volatile organic compounds (VOCs) emitted from biogenic or anthropogenic sources, contributes a large fraction of this material. In the particle phase, these products can undergo accretion reactions to form oligomers that impact the formation, composition, and chemical-physical properties of aerosols. While these reactions are known to occur in the atmosphere, data and models describing their kinetics and equilibria are sparse. Here, reactions of compounds containing potentially reactive hydroperoxide, hydroxyl, carboxyl, aldehyde, and ketone groups were investigated in single and phase-separated organic/aqueous mixtures in the absence and presence of a sulfuric acid catalyst. Compounds containing these groups and a nonreactive UV-absorbing nitrate group were synthesized and their reactions and products were monitored and characterized using high-performance liquid chromatography with UV detection (HPLC-UV), electrospray ionization-mass spectrometry (ESI-MS) and attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy. Reactions were observed between hydroperoxides and aldehydes to form peroxyhemiacetals, and between carboxylic acids and alcohols to form esters, and their rate and equilibrium constants were determined. No reactions were observed in other mixtures, indicating that under the conditions of these experiments only a few reaction pathways form oligomers. Reactions were also conducted with probe compounds and SOA formed in an environmental chamber reaction of α-pinene with O3 SOA. Whereas in a previous study we observed a rapid hydroperoxide reaction in this SOA, among the other compounds studied here only alcohols reacted. These results provide insight into the types of accretion reactions that are likely to occur in atmospheric aerosols, and the rate and equilibrium constants can be used to better model SOA chemistry."

In the immediate aftermath of the fire, there was an intense interest in accessing the persistent air quality effects of the fire both due to its close proximity to major population centers as well as the unique nature of the fire fuel, mostly man-made structures as opposed to biomass. While smoke emissions from traditional wildfires have been well studied and characterized, the emissions from building materials are less well understood and can vary significantly based on the structure. We are interested in how the smoke emissions from this fire infiltrated and then interacted in indoor environments, which have large surface reservoirs, leading to potential persistent indoor air quality effects. In the weeks following the fire, multiple instruments were deployed in a smoke-impacted home immediately adjacent to one of the burn areas to monitor effects for a period of roughly a month. Our measurements focused on gas phase Volatile Organic Chemicals (VOCs) and were carried out with a Vocus Proton-Transfer-Reaction Time-of-Flight Mass Spectrometer (Vocus PTR-TOF) and Aerodyne Gas Chromatograph (GC). Both indoor and outdoor levels were measured to look at long term trends and indoor enhancements. Ventilation experiments as well as mitigation tests using Corsi-Rosenthal boxes were done, and analyzed with respect to changes in indoor VOC concentration and exposure. Smoke remediation took place during the study, and the data give insight into enhancements in VOCs before, during, and after the cleaning.

These forcings have dramatically changed the structure and function of Earth’s ecosystems and threaten our life support systems—air, land, and water. Creating a path to a livable future requires drawing on scientific approaches across the Earth and environmental sciences and integrating the results of that research into creative, multi-faceted solutions. This is use-inspired research. In my talk, I will discuss how my research group and I have developed projects that cut across biogeochemistry, hydrology, and critical zone science to address both fundamental questions about how ecosystems work and are changing, as well as collaborating with land managers, policymakers, and regulators to create solutions for sustainable land management. Highlights include: (1) developing novel isotopic methods to advance understanding of modern changes to sulfur (S) cycling; (2) informing pesticide and water management in California; (3) integrating geophysics with measurements of reactive elements (C, N, S, and Hg) to determine how melting subsurface ice features will alter biogeochemical processes, as well as the health of wildlife in remote alpine areas; and (4) designing international observatory networks that foster broader participation in science and yield data availability where few humans go. Throughout the talk, I will also share the motivation for my own journey as a scientist, my vision for a productive research program within CIRES, and the potential that I see for fruitful collaboration across the Institute. Dr. Hinckley is an Assistant Professor and Associate Chair of Undergraduate Students in the Department of Environmental Studies and a Fellow of the Institute of Arctic and Alpine Research.

Abstract: When trying to adapt to a changing climate, with all the inherent uncertainties about how the future may play out, resource managers often turn to scenario planning as a tool. Managers use scenario planning to explore plausible ways the climate may change, allowing them to work with climate change uncertainty rather than being paralyzed by it. Once identified, scenarios of the future are used to develop proactive measures to prepare for and adapt to scenarios of change. A key part of scenario planning is generating a list of potential future climates we may experience. This webinar will describe and compare different approaches to generate the climate futures and identify an approach that captures a broad range of climate conditions (a key ingredient to developing scenarios) across both near and long-term planning horizons. We then will describe tools for creating reproducible climate futures, including an R package and training materials that enables users to develop their own projections, and provide guidance on their use. Over the past decade, we have operationalized the generation of climate futures and with the recent development of the Reproducible Climate Futures (RCF) R package, standardized and streamlined their production. We have found climate futures and scenarios offer an adaptable approach to planning across a broad range of management contexts. About the speakers: David Lawrence specializes in aquatic ecology and has worked as a climate change scientist within the National Park Service Climate Change Response Program since 2017. In this role David conducts and translates climate change research to support forward-looking land and water management. David has a PhD in ecology from the University of Washington. Amber Runyon is an ecologist for the National Park Service Climate Change Response Program where she collaborates with park managers to provide management-relevant projections of future-climate that serve as the basis for climate-informed planning. Amber has a PhD in ecology from Colorado State University.

	Atmospheric Chemistry Program Seminar Atmospheric Chemistry Program Seminar New approaches to ambient ion analysis reveal chemical trends Daniel Katz, ANYL 3rd year, Browne group "Atmospheric ions control the electrical properties of the atmosphere, influence chemical composition via ion-molecule and/or ion-catalyzed reactions, and affect new particle formation. Understanding the role of ions in these processes requires knowledge of ionic chemical composition. However, determining the chemical composition of these ions is analytically challenging owing to the low concentration of ambient ions in the atmosphere (~100s-1000 ions/cm 3 ). Here, we analyze measurements of the composition of ambient cations and anions collected using an atmospheric pressure interface time-of-flight mass spectrometer (APi-TOF) during the 2016 Holistic Interactions of Shallow Clouds, Aerosols, and Land- Ecosystems (HI-SCALE) campaign. We utilize a newly developed technique, binned positive matrix factorization (binPMF), in conjunction with Resolution-enhanced Kendrick Mass Defect (REKMD) analysis. These techniques allowed for improved chemical insight into the trends in ion composition with no requirement for a priori assignments of chemical composition. This advancement is of particular importance for measurements with low signal-to-noise. Mass spectral factors were first identified by binPMF and then analyzed using REKMD plots to elucidate chemical patterns within the factors. REKMD demonstrated that otherwise unidentified compounds were related by repeating units of CH 2 and O. Back trajectories and correlation with other measurements provide insight into potential sources of the various identified factors. Overall, we demonstrate that binPMF in combination with REKMD is a powerful tool to analyze challenging mass spectrometric datasets."

In addition to the Reports of the three IPCC Working Groups, three additional Special Reports were produced as part of AR6, including the Special Report on Oceans and Cryosphere in a Changing Climate (SROCC). In this presentation, I’ll revisit the key messages from SROCC (completed in 2019) in the context of the more recent Working Group I assessment (completed in 2021). These key messages span observed and projected changes to the cryosphere, attribution of these changes to human influence on the climate system, and the impacts of a changing cryosphere on the polar regions and across the entire planet. I’ll also provide an overview of the IPCC process, including reflections as both an SROCC author and national delegate to the Working Group I and II approval process.

Atmospheric Chemistry Program Seminar

Atmospheric Chemistry of Volatile Methyl Siloxanes – Kinetics and Oxidation Mechanism from Experimental and Theoretical Investigations

Mitchell Alton, ANYL PhD thesis defense,
Browne group

"Volatile methyl siloxanes (VMS) are solely anthropogenic chemicals that have come under recent scrutiny for their environmental persistence and tendency to bioaccumulate. Millions of tons of these chemicals are produced every year, with an estimated 30 kilotons of decamethylcyclopentasiloxane (D5) emitted into the environment every year, with additional contributions from other VMS. A large source of VMS to the environment is from use of personal care products containing these compounds. Due to environmental concerns about the impact of these compounds, the European Union placed restrictions on the quantity of VMS in wash-off personal care products in 2018 with recommendations to increase the restrictions to include some industrial processes in 2021. Although there is significant interest in these high-production chemicals, the understanding of the environmental fate of these compounds is incomplete. It is predicted that >90% of VMS released to the environment will partition into the atmosphere. Once these compounds are in the atmosphere, they can react with hydroxyl radicals (OH) or chlorine atoms (Cl) through hydrogen-abstraction reactions, though the previously reported rate constants for reactions with OH vary by more than a factor of 3 and only one measurement exists for the rate constant with Cl atoms. Additionally, previously published works reported inconsistent oxidation products of these compounds, likely due to unconstrained oxidation chemistry in their experiments. To better constrain the atmospheric chemistry and fate of these compounds, I measured the kinetics of seven VMS with OH radicals and Cl atoms in a 1 cubic meter FEP Teflon™ chamber I designed and built. Additionally, I measured the oxidation products of VMS in a variety of atmospheric conditions to better constrain the oxidation mechanism. Finally, I used quantum theoretical calculations to investigate the plausibility of the reactions proposed from our experimental results."

Atmospheric Chemistry Program Seminar

Kinetics of Oligomer-Forming Reactions Involving the Major Functional Groups Present in Atmospheric Secondary Organic Aerosol Particles

Hannah Maben, ANYL Master's Thesis Defense,
Ziemann group

"Atmospheric organic aerosol particles impact climate as well as human and environmental health. Secondary organic aerosol (SOA), which is formed by the gas-to-particle partitioning of products of the oxidation of volatile organic compounds (VOCs) emitted from biogenic or anthropogenic sources, contributes a large fraction of this material. In the particle phase, these products can undergo accretion reactions to form oligomers that impact the formation, composition, and chemical-physical properties of aerosols. While these reactions are known to occur in the atmosphere, data and models describing their kinetics and equilibria are sparse. Here, reactions of compounds containing potentially reactive hydroperoxide, hydroxyl, carboxyl, aldehyde, and ketone groups were investigated in single and phase-separated organic/aqueous mixtures in the absence and presence of a sulfuric acid catalyst. Compounds containing these groups and a nonreactive UV-absorbing nitrate group were synthesized and their reactions and products were monitored and characterized using high-performance liquid chromatography with UV detection (HPLC-UV), electrospray ionization-mass spectrometry (ESI-MS) and attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy. Reactions were observed between hydroperoxides and aldehydes to form peroxyhemiacetals, and between carboxylic acids and alcohols to form esters, and their rate and equilibrium constants were determined. No reactions were observed in other mixtures, indicating that under the conditions of these experiments only a few reaction pathways form oligomers. Reactions were also conducted with probe compounds and SOA formed in an environmental chamber reaction of α-pinene with O3 SOA. Whereas in a previous study we observed a rapid hydroperoxide reaction in this SOA, among the other compounds studied here only alcohols reacted. These results provide insight into the types of accretion reactions that are likely to occur in atmospheric aerosols, and the rate and equilibrium constants can be used to better model SOA chemistry."

Measurements of VOCs in Homes Impacted by Smoke from the Marshall Fire

William Dresser, ANYL 3rd year,
de Gouw group

"The Marshall Fire was one of the most destructive fires in Colorado history, and burned and damaged over 1000 structures in Boulder County. In the immediate aftermath of the fire, there was an intense interest in accessing the persistent air quality effects of the fire both due to its close proximity to major population centers as well as the unique nature of the fire fuel, mostly man-made structures as opposed to biomass. While smoke emissions from traditional wildfires have been well studied and characterized, the emissions from building materials are less well understood and can vary significantly based on the structure. We are interested in how the smoke emissions from this fire infiltrated and then interacted in indoor environments, which have large surface reservoirs, leading to potential persistent indoor air quality effects. In the weeks following the fire, multiple instruments were deployed in a smoke-impacted home immediately adjacent to one of the burn areas to monitor effects for a period of roughly a month. Our measurements focused on gas phase Volatile Organic Chemicals (VOCs) and were carried out with a Vocus Proton-Transfer-Reaction Time-of-Flight Mass Spectrometer (Vocus PTR-TOF) and Aerodyne Gas Chromatograph (GC). Both indoor and outdoor levels were measured to look at long term trends and indoor enhancements. Ventilation experiments as well as mitigation tests using Corsi-Rosenthal boxes were done, and analyzed with respect to changes in indoor VOC concentration and exposure. Smoke remediation took place during the study, and the data give insight into enhancements in VOCs before, during, and after the cleaning. "

Special Seminar: Eve Hinckley

A Use-Inspired Approach to Ecosystem Science in the Anthropocene

Eve Hinckley

Abstract: We now live in an era characterized predominately by our influence on the planet—the Anthropocene—with rising air temperatures, accelerated biogeochemical cycles, and widespread disturbances, such as wildfire. These forcings have dramatically changed the structure and function of Earth’s ecosystems and threaten our life support systems—air, land, and water. Creating a path to a livable future requires drawing on scientific approaches across the Earth and environmental sciences and integrating the results of that research into creative, multi-faceted solutions. This is use-inspired research. In my talk, I will discuss how my research group and I have developed projects that cut across biogeochemistry, hydrology, and critical zone science to address both fundamental questions about how ecosystems work and are changing, as well as collaborating with land managers, policymakers, and regulators to create solutions for sustainable land management. Highlights include: (1) developing novel isotopic methods to advance understanding of modern changes to sulfur (S) cycling; (2) informing pesticide and water management in California; (3) integrating geophysics with measurements of reactive elements (C, N, S, and Hg) to determine how melting subsurface ice features will alter biogeochemical processes, as well as the health of wildlife in remote alpine areas; and (4) designing international observatory networks that foster broader participation in science and yield data availability where few humans go. Throughout the talk, I will also share the motivation for my own journey as a scientist, my vision for a productive research program within CIRES, and the potential that I see for fruitful collaboration across the Institute.

Dr. Hinckley is an Assistant Professor and Associate Chair of Undergraduate Students in the Department of Environmental Studies and a Fellow of the Institute of Arctic and Alpine Research.

NC CASC Webinar Series: Tools for Developing Reproducible Climate Futures for Resource Planning

Presented by:

David Lawrence, National Park Service

Amber Runyon, National Park Service

Other co-authors:

John Gross, National Park Service

Gregor Schuurman, National Park Service

Brian Miller, U.S. Geological Survey, North Central CASC

Joel Reynolds, National Park Service

Please register in advance for this meeting: https://cuboulder.zoom.us/meeting/register/tJYrduGrpj4iE9INQlaV2SclWlQu123wURPH

After registering, you will receive a confirmation email containing information about how to join the meeting.

Abstract:

When trying to adapt to a changing climate, with all the inherent uncertainties about how the future may play out, resource managers often turn to scenario planning as a tool. Managers use scenario planning to explore plausible ways the climate may change, allowing them to work with climate change uncertainty rather than being paralyzed by it. Once identified, scenarios of the future are used to develop proactive measures to prepare for and adapt to scenarios of change. A key part of scenario planning is generating a list of potential future climates we may experience. This webinar will describe and compare different approaches to generate the climate futures and identify an approach that captures a broad range of climate conditions (a key ingredient to developing scenarios) across both near and long-term planning horizons. We then will describe tools for creating reproducible climate futures, including an R package and training materials that enables users to develop their own projections, and provide guidance on their use. Over the past decade, we have operationalized the generation of climate futures and with the recent development of the Reproducible Climate Futures (RCF) R package, standardized and streamlined their production. We have found climate futures and scenarios offer an adaptable approach to planning across a broad range of management contexts.

About the speakers:

David Lawrence specializes in aquatic ecology and has worked as a climate change scientist within the National Park Service Climate Change Response Program since 2017. In this role David conducts and translates climate change research to support forward-looking land and water management. David has a PhD in ecology from the University of Washington.

Amber Runyon is an ecologist for the National Park Service Climate Change Response Program where she collaborates with park managers to provide management-relevant projections of future-climate that serve as the basis for climate-informed planning. Amber has a PhD in ecology from Colorado State University.

Atmospheric Chemistry Program Seminar

New approaches to ambient ion analysis reveal chemical trends

Daniel Katz, ANYL 3rd year,
Browne group

"Atmospheric ions control the electrical properties of the atmosphere, influence chemical composition via ion-molecule and/or ion-catalyzed reactions, and affect new particle formation. Understanding the role of ions in these processes requires knowledge of ionic chemical composition. However, determining the chemical composition of these ions is analytically challenging owing to the low concentration of ambient ions in the atmosphere (~100s-1000 ions/cm 3 ). Here, we analyze measurements of the composition of ambient cations and anions collected using an atmospheric pressure interface time-of-flight mass spectrometer (APi-TOF) during the 2016 Holistic Interactions of Shallow Clouds, Aerosols, and Land- Ecosystems (HI-SCALE) campaign. We utilize a newly developed technique, binned positive matrix factorization (binPMF), in conjunction with Resolution-enhanced Kendrick Mass Defect (REKMD) analysis. These techniques allowed for improved chemical insight into the trends in ion composition with no requirement for a priori assignments of chemical composition. This advancement is of particular importance for measurements with low signal-to-noise. Mass spectral factors were first identified by binPMF and then analyzed using REKMD plots to elucidate chemical patterns within the factors. REKMD demonstrated that otherwise unidentified compounds were related by repeating units of CH 2 and O. Back trajectories and correlation with other measurements provide insight into potential sources of the various identified factors. Overall, we demonstrate that binPMF in combination with REKMD is a powerful tool to analyze challenging mass spectrometric datasets."

NSIDC Cryosphere Seminar

Assessment of a changing cryosphere in the IPCC Sixth Assessment cycle: process, key messages, and the path forward presented by Dr. Chris Derksen

Abstract: The Sixth Assessment Cycle (AR6) of the Intergovernmental Panel on Climate Change (IPCC) is nearly complete. In addition to the Reports of the three IPCC Working Groups, three additional Special Reports were produced as part of AR6, including the Special Report on Oceans and Cryosphere in a Changing Climate (SROCC). In this presentation, I’ll revisit the key messages from SROCC (completed in 2019) in the context of the more recent Working Group I assessment (completed in 2021). These key messages span observed and projected changes to the cryosphere, attribution of these changes to human influence on the climate system, and the impacts of a changing cryosphere on the polar regions and across the entire planet. I’ll also provide an overview of the IPCC process, including reflections as both an SROCC author and national delegate to the Working Group I and II approval process.

Bio: Chris Derksen is a research scientist with the Climate Research Division of Environment and Climate Change Canada. His research activities focus on the use of satellite data and climate models to understand climate change impacts on the Arctic. Chris has participated in numerous snow and sea ice field campaigns across the Canadian Arctic. He is the science lead for a new satellite radar mission under development with the Canadian Space Agency, and was a lead author of the International Panel on Climate Change (IPCC) Special Report on Oceans and Cryosphere in a Changing Climate.

Special speaker this week. ESOC coffee hour is meeting in person. Weekly 9-10am on Wednesdays in the ESOC Reading Room, Ekeley W230. Please email Claire Waugh (waughc@colorado.edu) for information.

Title: Linking processed imagery from Google Earth Engine using USGS river gage data: Improvements for river morphology studies in the RIMORPHIS project

Toby Minear and Sarah Lundell will be speaking about a project focused on building the “Finding Images from Linked Hydrology”, or FILH tool to filter Landsat and Sentinel-2 optical imagery from Google Earth Engine using hydrologic information, in this case from the USGS National Water Information System. The developed filter includes finding images during periods that exceed a user-input discharge threshold, or images within a range of discharges as well as determining dates of usable satellite imagery (e.g. overpass, cloud cover, etc). The FILH tool enables the analysis of water extent based on discharge rates but could be modified to include other river information if desired (e.g. measured river widths, velocities, stage, etc.) and is being incorporated into the NSF-funded River Morphology Information System (rimorphis.org).

ESOC researchers, post-docs and graduate students gather for conversation and to discuss research. Occasional guest speakers are invited to give short presentations on topics of interest.
