The AGU 2020 Fall Meeting has gone virtual, with some Town Halls and sessions starting on December 1.
The bulk of the presentations, however, start on Monday, December 7. And many ASR- funded scientists will be fully participating and sharing their research with the AGU community with over 100 presentations and posters, as well as leading session and town halls. AGU is an important venue to share ASR results.
See the full slate of ASR-connected presentations.
Following are select presentations and town halls of interest to the ASR community. Please don’t forget to check out the many additional oral presentations and poster sessions listed in the link above.

Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) Expedition
The MOSAiC expedition set out to document the atmosphere, sea ice, ocean, biogeochemistry, and ecosystem in the central Arctic. More than 400 field participants and 60 institutions from 20 countries were active in the expedition from September 2019 to October 2020. MOSAiC’s central observatory was the icebreaker R/V Polarstern, which froze into and then drifted with the arctic sea ice for most of the year.
Matthew Shupe, an ASR-funded principal investigator and a co-coordinator of the MOSAiC expedition, will be the primary convener of the following MOSAiC- and Arctic-themed AGU sessions:

Cloud Aerosol, and Complex Terrain Interactions (CACTI) Campaign
From October 2018 through April 2019, CACTI—led by ASR-funded scientist Adam Varble—collected ground and aerial data to explore the life cycles of convective clouds in Argentina’s Sierras de Córdoba mountain range. This area is said to spawn the biggest thunderstorms in the world. The campaign featured the first deployment of the second-generation C-Band Scanning ARM Precipitation Radar, which delivers slice-like flat images of the atmosphere. CACTI ran concurrently with Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations (RELAMPAGO), a campaign funded largely by the National Science Foundation.
With 80 days of deep convection observed, CACTI represents a new wealth of measurements on cloud dynamics and microphysics, ambient thermodynamic and kinematic and surface conditions, and properties of aerosols. The next scenario of focus for the Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) activity will be deep convection during CACTI.
Note: Each presentation is scheduled to run no longer than five minutes, so the full session times are listed below for planning purposes.

Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA)
For a better understanding of aerosols and low clouds in the remote marine environment, ACE-ENA used measurements from ARM’s Eastern North Atlantic observatory in the Azores and data from ARM’s now-retired Gulfstream-159 (G-1) research aircraft. The campaign took place during two intensive operational periods in summer 2017 and winter 2018.
A new joint special issue on marine aerosols, trace gases, and clouds over the North Atlantic includes findings from ACE-ENA. Several papers in the issue will be presented during AGU.
