Atmospheric Chemistry Program Seminar

Chemistry of Organic Compounds in the Atmosphere and Indoor Air

Paul Ziemann,
ANYL Faculty, CU Boulder (1/2 seminar)

"Laboratory studies provide much of the fundamental data on reaction kinetics, products, and mechanisms that are needed to understand atmospheric and indoor air chemistry and to develop models that are used to establish air quality regulations and predict the effects of human activities. Research in my laboratory focuses primarily on environmental chamber studies of the atmospheric chemistry of organic compounds emitted from natural and anthropogenic sources and the physical and chemical processes by which oxidized organic reaction products form aerosol particles. In addition to this we have conducted a number of collaborative studies of indoor air chemistry at CU."

Seminar begins at 12:40. Please contact Anne.Handschy@colorado.edu for the remote link.

MOSAiC: A Year on Ice

MOSAiC: A Year on Ice

From September 2019 to October 2020, the German icebreaker Polarstern was embedded within the Arctic sea ice and drifted for 12 months. Hundreds of scientists from around the world spent months aboard, in shifts, studying the complete Arctic climate “system” including the ocean below, sea ice, and the atmosphere above. 

Polar bears disrupted their work, wandering through small scientific “cities” on the ice and forcing people to scramble back to the ship. An arctic fox chewed through cables. And storms swirled through, breaking up the sea ice underfoot (and under instruments). 

CU Boulder scientists played leading roles in the mission, dubbed MOSAiC for Multidisciplinary Drifting Observatory for the Study of Arctic Climate. Today, as part of Research & Innovation Week, you’ll hear from expedition co-coordinator and lead atmospheric scientist Matthew Shupe; two educators who worked with dozens of MOSAiC scientists to bring their insights to students; and a videography team who captured mission moments in 360° degrees, creating planetarium shows that will be viewed around the world. 

Panelists will take live questions from the audience. There will be plenty of time for engagement.

This Zoom event was recorded, and can be watched here

Measurement, Knowledge, and Representation of Arctic Sea Ice by Laura Seddon, Department of Geography at Durham University

Abstract: Satellite-derived sea-ice products and datasets are instrumental tools in the reporting of Arctic sea-ice conditions. Through numerical and visual representations, these products have contributed significantly to our understanding of Arctic sea-ice characteristics and variability, knowledge of which is critical for a wide range of applications including operational forecasting and climate research. They have also influenced how the region is framed within broader political and socio-economic contexts. However, the complex and dynamic nature of sea ice is difficult to measure and this requires the application of a number of assumptions and simplifications in data acquisition, processing, and classification. Moreover, differences in these scientific practices can result in different representations of sea-ice conditions. These differences raise important questions over the nature of the underlying decisions, methods, assumptions, and conventions that inform the production of knowledge about complex and changing environments, as well as about the linked ways in which both science and policy (and the institutions that join them) manage the uncertainties in sea-ice observation. This talk introduces my PhD research which explores these issues using an interdisciplinary approach. The research draws upon ideas from the physical sciences, science and technology studies, and critical cartography to examine and compare various sea-ice data products, as well as the social contexts in which they are constructed. The aim is to gain insights into how dynamic and indeterminate geophysical data is acquired, processed, and reported in Arctic sea-ice science, in order to contribute to a wider understanding of the sociological nature of scientific knowledge.

Brief introduction: Laura Seddon is a PhD student in the Department of Geography at Durham University and a member of the Durham Arctic Research Centre for Training and Interdisciplinary Collaboration (DurhamARCTIC), where her research examines the nature of satellite-derived sea-ice products and the knowledge they produce about the changing Arctic region.

Getting to Know the Faces of Industry

Getting to Know the Faces of Industry

So you are doing a PhD or working on a postdoc. Are you unsure about what you want to do after? Are you debating industry vs. academia? Working at a university provides a lot of experience in the academic world, but what do you really know about the opportunities in industry?

This CIRES Graduate Association event is designed to connect students and post-docs to professionals working in all sectors of industry. “Virtually” come and talk with a few professionals who know what you are going through. They can identify with the graduate school process and talk about differences between academia and industry.

Join us next week on Tuesday, October 20th from 4-5:30 pm and learn about all the different kinds of opportunities that are outside of academia or even adjacent to academia.

Variability and diel dependence of O 3 – NO x – VOC chemistry in western wildfire plumes: Results from the NOAA Twin Otter during FIREX-AQ

Michael Robinson, ANYL 1st year

"The variability in photochemical ozone production from western wildfire plumes is important to the accurate prediction of their influence on North American air quality. A set of photochemical measurements including ozone, nitrogen oxides, photolysis rates and a suite of volatile organic compounds (VOCs), were made from the NOAA Twin Otter research aircraft as a part of the Fire Influence on Regional to Global Environments and Air Quality (FIREX-AQ) experiment. This research aircraft sampled nine unique fire complexes in five western states. Typical research flight days included flights during the afternoon, evening and night. In general, observed ozone production in the sampled plumes is rapid, reaching maximum ozone within 30 minutes downwind. A 0-D box modeling tool was developed to further probe the chemistry driving ozone production in these plumes. This tool was used to calculate afternoon and evening ozone isopleths which allows for a comparison of each individual fire complex in a common framework. The analysis shows the sensitivity of ozone production to initial NOx and VOC emissions. However ozone isopleths are not capable of describing the temporal transition of NO x and VOC sensitive chemical regimes. A radical budget approach is used for probing the temporal evolution of the chemistry. Afternoon photochemical plumes display a rapid transition from VOC sensitive chemistry to NO x sensitive chemistry, mainly driven by radical production from photolysis of HCHO and HONO emitted directly from the fire. Evening photochemical plumes exhibit a slower transition from NO x sensitive chemistry to VOC sensitive chemistry, with a larger portion radical production from alkene ozonolysis."

Model Inter-comparisons of Inorganic Nitrate Formation During KORUS-AQ Campaign

Seonsik Yun, ANYL 1st year

"Nitrogen oxides play an important role in global tropospheric chemistry. The lifetime of nitrogen oxides is controlled by organic and inorganic nitrate formation. GEOS-Chem, a global 3-D chemical transport model, has historically had an over-estimation problem of inorganic nitrates relative to surface observation networks. This study investigated this problem by using model inter-comparisons with six different chemical transport model simulations during the KORUS-AQ field campaign period. N2O5 hydrolysis reaction, a primary nocturnal inorganic nitrate formation, was investigated to compare differences in calculations of inorganic nitrate formation between the model simulations. Differences in heterogeneous loss of N2O5 between the models were analyzed with the uptake coefficient, aerosol surface area density, and N2O5 concentration. Results show that high N2O5 concentrations at nighttime in GEOS-Chem could be attributed to the high O3 concentrations at nighttime compared to the Ensemble model, which can contribute to the over-estimation of inorganic nitrates in GEOS-Chem."
