Innovative Research Program

Innovative Research Program

The Innovative Research Program is designed to stimulate a creative research environment within CIRES and to encourage synergy between disciplines and research colleagues. The intent is to support small research efforts that can quickly provide concept viability or rule out further consideration. The program encourages novel, unconventional or fundamental research that might otherwise be difficult to fund. Funded projects are inventive, sometimes opportunistic, and do not necessarily have an immediate practical application or guarantee of success. This program supports pilot or exploratory studies, which may provide rapid results. Activities are not tightly restricted and can range from instrument development, lab testing, and field observations to model development, evaluation, and application.

The 2022 IRP competition opens February 14, 2022. Applications will be due March 28, 2022Submit your proposal online. You must have a CIRES login and password to access the online application.

January 2022 update: CIRES is instituting a "Rapid IRP" to provide funds for research activities that are time-sensitive and urgent. Potential CIRES proposers should see the email or reach out to the Associate Director for Science for more information.

Atmospheric Chemistry Program Seminar

Atmospheric Chemistry Program Seminar

Longer term aging of organic aerosol: photobleaching and chemical transformations

Rachel O'Brien,
College of William and Mary

"Organic aerosol particles can influence the climate through either directly absorbing or scattering solar radiation or by acting as nuclei for cloud droplets. Some aerosol particles are dominantly scattering while others contain organic molecules that can absorb solar radiation in the visible region, termed brown carbon (BrC). We still have large uncertainties in the magnitude of these climate effects and a better understanding of the removal rates for the particle mass and absorption properties (i.e. color) is needed. One removal process is photolysis, where absorption of solar radiation leads to fragmentation of the organic molecules and the loss of particle mass and/or color. However, the photolysis rates and the overall extent of mass that can be removed via direct photolysis in laboratory experiments does not match what is used in models and often differs from ambient measurements. In this talk, I will combine results from work in our lab looking at photolysis of biogenic secondary organic aerosol as well as BrC from biomass burning organic aerosol to evaluate gaps in our ability to predict the observed ambient removal rates. By probing complex mixtures from recent biomass burning experiments (e.g. FIREX samples), I will demonstrate that our current measured rates in the laboratory are overestimated and that a slower photolysis rate, as well as a potential gas-phase oxidation rate, should be used to predict the role of photolysis on organic aerosol lifetime in the atmosphere."

NSIDC Cryosphere Seminar

NSIDC Cryosphere Seminar

High mountain biodiversity under climate change: progress, challenges, and promise by Dr. Scott Hotaling

Abstract: Climate change is dramatically altering mountain ecosystems worldwide. In high-elevation regions, perhaps the most consequential change is the rapid recession of glaciers and perennial snowfields. How a changing cryosphere will impact biodiversity, particularly in glacier and meltwater-driven habitats, is poorly known. In this seminar, I will integrate community ecology, ecophysiology, and molecular tools to give a broad overview of the existing biodiversity in high mountain habitats, its potential fate under climate change, and the evidence for in situ refugia to buffer these changes.

Bio:  Scott Hotaling is currently a postdoc in the School of Biological Sciences at Washington State University but in Summer 2022, he’ll be starting a new lab at Utah State University in the Dept. of Watershed Sciences. He received a PhD in 2017 from the University of Kentucky (Advisor: David Weisrock) and has a BS from North Carolina State University (2011). In 2015, he co-founded the Teton Alpine Stream Research project which is dedicated to using long-term ecological monitoring to quantify how mountain aquatic ecosystems are changing. He is also a big fan of Twitter (@MtnScience).

Building your mentor network

Building your mentor network

Please join CGA members and Christine Wiedinmyer for our first Hidden Curricuculm seminar in the series to discuss building your network of mentors!

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 focuses on the informal “hidden curriculum” in graduate school that can complement formal student learning to help individuals lead successful research careers. 

The first seminar of this series will focus on how to build your network of mentors, lead by CIRES' own, Christine Wiedinmyer. She will discuss how to find and pick mentors in order to build the best supportive network. 

Please join us on Thursday February 17th @12:30 - 2 pm on zoom to hear some tips and ask your own questions. RSVP here by Wednesday at 11:59 pm MST in order to receive the zoom link on Thursday morning.

Atmospheric Chemistry Program Seminar

An Investigation of Carboxylic Acid Chemistry in Indoor and Outdoor Environments

Anna Ziola, ANYL 3rd year,
Ziemann group

"Carboxylic acids are prominent organic molecules in indoor and outdoor environments and also have chemical properties that make them useful probes for investigating the chemistry of indoor and outdoor air. Even though the average person spends nearly 90% of their lifetime indoors, we know very little about the processes that impact volatile organic compounds (VOCs) in indoor environments, where there are a variety of surfaces that VOCs can interact with. To understand the role of wood surfaces, we have used an iodide chemical ionization mass spectrometer (I-CIMS) and an attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectrometer along with a model to quantify and better understand how carboxylic acids interact with a variety of wood species and varnishes. These experiments have provided parameters for use in models and shown that the behavior of carboxylic acid VOCs indoors relies more on the identity of the varnish and less on the identity of the wood species. We have also taken advantage of the chemical properties of carboxylic acids to study the oxidation of alkenes in low NOx environments. According to data from CalNex in 2010 and LAAQS in 2020, the concentration of mid-day NO, a prominent component in VOC oxidation mechanisms, has decreased by about 75% in Los Angeles in the past decade. There have been many studies on the oxidation of VOCs in high NOx environments, but far fewer in the absence of NOx. To gather more knowledge about low NOx chemistry, we reacted 6-heptenoic acid, a C7 1-alkene with a terminal carboxylic acid group, with OH radicals in an environmental chamber while using an I-CIMS to identify and quantify gas-phase products. We also collected aerosol particles on filters, derivatized the carboxylic acid groups, and identified and quantified the products using high performance liquid chromatography (HPLC) in tandem with an electrospray ionization mass spectrometer (ESI-MS). Therefore, by taking advantage of carboxylic acid properties, we have been able to better understand their interactions with indoor surfaces and gain insights into the oxidation of alkenes under low NOx conditions."

Innovative Research Program

Innovative Research Program

The Innovative Research Program is designed to stimulate a creative research environment within CIRES and to encourage synergy between disciplines and research colleagues. The intent is to support small research efforts that can quickly provide concept viability or rule out further consideration. The program encourages novel, unconventional or fundamental research that might otherwise be difficult to fund. Funded projects are inventive, sometimes opportunistic, and do not necessarily have an immediate practical application or guarantee of success. This program supports pilot or exploratory studies, which may provide rapid results. Activities are not tightly restricted and can range from instrument development, lab testing, and field observations to model development, evaluation, and application.

The 2022 IRP competition opens February 14, 2022. Applications will be due March 28, 2022Submit your proposal online. You must have a CIRES login and password to access the online application.

January 2022 update: CIRES is instituting a "Rapid IRP" to provide funds for research activities that are time-sensitive and urgent. Potential CIRES proposers should see the email or reach out to the Associate Director for Science for more information.

Supervisor Training Series: Best Practices for ALL Supervisors

Please join CIRES HR for a Supervisors Best Practices training seminar on February 28 at 10 am.  If you are a supervisor, please attend, as this training is relevant for all CIRES supervisors regardless of how long you have been a supervisor. Many things have evolved over the years on hiring, career development, and annual evaluations, leave reporting and more. This training will give you resources and foundational knowledge that is critical for both you and your supervises.

Session will be recorded and posted here once video has been processed for those who are unable to attend at the time of the event.

Reduction of Iodate in aqueous organic and inorganic thin films

Margarita Reza, ANYL 3rd year,
Volkamer group

"Iodine species are known to catalytically destroy ozone, and in the case of Iodic acid (HIO3), efficiently forms particles. Iodic acid is a source of particulate iodate (IO3-); this has been detected in aged stratospheric air alongside gas-phase IO radical, suggesting the existence of recycling mechanisms reducing IO3- to form volatile iodine species. The reduction of iodate is explored through a series of photochemical coated wall flow tube (CWFT) experiments. A quartz glass tube was coated with an aqueous solution containing sodium iodate in a matrix (i.e., either ammonium bisulfate (ABS), 1,2,3,4-butanetetracarboxylic acid (BTCA), citric acid (CA), or Fe(III) citrate (Fe-Cit) and CA) at a concentration ratio iodate:matrix = 1:100. A thin aqueous film forms on the inside walls by passing a stream of humidified air through the CWFT (~80% RH). For each film, the formation of gaseous iodine (I­2) was followed in three types of experiments: (1) dark reaction with H2O2 involved flowing H2O2 through the CWFT for several hours in the dark; (2) photochemical experiments involved irradiating the CWFT with visible lights and UVA lights, separately; and (3) dark-aging experiments involved flowing H2O2 through the CWFT for several hours in the dark, followed by irradiation with visible light. The evaporation of gas-phase I2 from the aqueous films was measured by cavity enhanced differential optical absorption spectroscopy (CE-DOAS) coupled to the CWFT. The cleanliness of the materials, cleaning procedures used, and the absence of uncontrolled chromophores reducing iodate, that might be intrinsic to the CWFT setup was confirmed in blank experiments. The I2 released from aged films irradiated with visible light (type 3 experiments) was found to be substantially greater than that from irradiated fresh films (type 2), or fresh films exposed to H2O2 in the dark (type 1). This increase of I2 in H2O2 aged films, independently observed in both inorganic and organic matrices, suggests that a secondary inorganic chromophore is formed from the reaction of iodate with H2O2. A photochemical pathway was discovered in which visible light is sufficient for reducing iodate to I2. This is relevant in the atmosphere because it helps to explain the co-existence of particulate IO3- and gas-phase IO radicals recently observed by aircraft measurements in the stratosphere. Multiphase re-cycling of I2 from particulate IO3- in absence of ultraviolet light further suggests that a catalytic reaction cycle is more active than previously thought, and involves three steps: (1) gas-phase HIO3 formation from I2 photolysis, (2) condensation and dissociation of HIO3 to form IO3-, and (3) IO3- reduction to re-cycle I2. This catalytic reaction cycle destroys O3 by multiphase chemistry, and highlights a possible catalytic role of HIO3 in particle formation. This photochemistry is currently missing in atmospheric models, seems relevant to predictions about the partitioning of iodine between the gas- and particle phases, invigorates particle formation from iodine oxoacids, and seems relevant to better understand iodine’s role in the recovery of the ozone layer."
