Picture a Scientist documentary - a discussion in our community

Picture a Scientist documentary - a discussion in our community

Presented by CU Boulder, CIRES, CGA, GSAB, WiSE, INSTAAR, GeoSMART, GSGA, and the Geology DEI Committee

There will be a screening of a new documentary called Picture a Scientist. Picture a Scientist chronicles the groundswell of researchers who are writing a new chapter for women scientists. Biologist Nancy Hopkins, chemist Raychelle Burks, and geologist Jane Willenbring lead viewers on a journey deep into their own experiences in the sciences, ranging from brutal harassment to years of subtle slights. Along the way, from cramped laboratories to spectacular field stations, we encounter scientific luminaries - including social scientists, neuroscientists, and psychologists - who provide new perspectives on how to make science itself more diverse, equitable, and open to all.

Following screening the movie we will meet to discuss the documentary ‘Picture a Scientist’, our reactions, specific topics, and how each of the journeys portrayed in the documentary has affected and impacted each of us and our community.

In order to screen this movie, event attendees must RSVP in order to receive the movie link and password by January 6th.

Screening dates: Saturday Jan 9th to Tuesday Jan 12th.
Discussion event: Tuesday January 12th, 2021 from 12-2pm MT

Atmospheric Chemistry Program Seminar

Atmospheric Chemistry Program Seminar

Peroxy radicals are getting curiouser and curiouser

Prof Neil Donahue,
Carnegie Mellon University

"Organic peroxy radicals sit at the center of tropospheric chemistry. Essentially all oxidation processes produce peroxy radicals immediately after an oxidant attacks a stable organic molecule. They have gas-phase lifetimes ranging from 1-1000 seconds. They also have choices; peroxy radical branching defines tropospheric chemistry. In the textbook case, they can react either with hydroperoxy radicals or with nitric oxide, either terminating as hydroperoxides or propagating to dark places that only Paul Ziemann understands while producing nitrogen dioxide and ultimately ozone. However, we have recently found that organoperoxy radicals with additional oxygenated functional groups can undergo progressive “autoxidation” (oxidation in the presence of molecular oxygen only) via internal hydrogen atom transfer and subsequent oxygen addition. These oxygenated organoperoxy radicals also appear to react with each other very rapidly (though this is uncertain) and to produce covalently bound organoperoxides (though this should be spin forbidden). Some of these products can have exceptionally low vapor pressures, and when formed in the gas phase can thus drive new-particle formation. It is possible that this is a major new-particle formation process in the pristine atmosphere, and that it was the dominant particle formation process in the pre-industrial atmosphere. In this talk I will explore recent experimental findings from the CLOUD experiment at CERN as well as modeling frameworks we have been developing to represent this chemistry and to translate chemical behavior observed in chambers to real-world conditions."

Cryosphere Seminar Series

Cryosphere Seminar Series

NSIDC’s Cryosphere Seminar “Interactions between the polar atmosphere and cryosphere: Observations and modeling” by Dr. John Cassano, Lead Scientist at the National Snow and Ice Data Center and CIRES Fellow

Coupling between the atmosphere and the surface is a critical aspect of the climate system. In the polar regions the atmosphere interacts with sea ice, ice sheet, ocean and land surfaces. The Cassano research group studies these interactions by conducting observational field campaigns, through analysis of atmospheric reanalysis and model datasets and by developing and applying regional climate models.

The atmospheric boundary layer modulates the exchange of heat, moisture, momentum and other properties between the atmosphere and the surface. We use a combination of automatic weather station (AWS), unmanned aerial systems (UAS) and other in-situ observations to study the polar atmospheric boundary layer. Examples from our work using data from a “tall tower” AWS and eight polar UAS campaigns will be presented. The UAS campaigns have been conducted throughout the annual cycle over ice sheet, sea ice and bare ground locations in the Antarctic from 2009 to 2017, and in the central Arctic Ocean as part of the MOSAiC (Multidisciplinary drifting Observations for the Study of Arctic Climate) expedition in 2020. Analysis of these data offers insights into the processes that control the thermodynamic state of the lower atmosphere and how the atmosphere interacts with the ice surface. These data also allow us to evaluate the ability of weather and climate models to reproduce observed boundary layer features and processes. 

Our modeling work has focused on the development and application of the Regional Arctic System Model (RASM). RASM is a fully coupled atmosphere – sea ice – ocean – land model. RASM, as well as atmospheric reanalysis and CMIP6 model data, are being used to study the interactions between cyclones and Arctic sea ice. RASM is also being used to study decadal predictability in the Arctic. Examples from both of these efforts will be shared during the presentation.

Dr. John Cassano is a Fellow at the Cooperative Institute for Research in Environmental Sciences, Lead Scientist at the National Snow and Ice Data Center, and Professor in the Department of Atmospheric and Oceanic Sciences at the University of Colorado, Boulder
