Editor’s note (December 23, 2020): Registrants for the 2020 AGU Fall Meeting can view presentations and recordings on the AGU virtual meeting platform through February 15, 2021.
By going virtual, the 2020 American Geophysical Union (AGU) Fall Meeting promises to be different than past meetings. With sessions spread out from December 1 to 17 to accommodate participants in multiple time zones, the amount of content might feel overwhelming. We make it easy for you to find ARM-relevant science during the meeting.
Below is a list of ARM-related AGU meeting highlights (all times Pacific; AGU login required to view abstract pages). Follow us on Twitter (@armnewsteam) and Facebook (@arm.gov) for a real-time guide to relevant activities using the hashtags #ARMAGU and #AGU20.
Go here to find more ARM-related presentations and posters, as well as sessions, talks, and posters related to Atmospheric System Research (ASR).
Add your presentation here to be featured on the ARM or ASR presentation web pages.
ARM is also hosting a virtual AGU booth, where you can get the full ARM AGU schedule, view facility materials, and meet with ARM representatives. Be sure to check out our booth in the Exhibit Hall! (See ARM’s exhibitor listing for more information.)
AGU has prepared a guide to the online meeting experience. Go to the AGU Fall Meeting website to learn more about session types and how content will be organized when you log on.
Talk to the ARM Data Center
ARM Data Center staff will be available in the virtual ARM booth to answer your questions about ARM data and give demonstrations of Data Discovery. During the week of December 7–11, ARM Data Center staff will be in the booth each day from 8–9 a.m. and 3–4 p.m.
Volunteer Request
Attendees interested in being volunteer judges for AGU Outstanding Student Presentation Awards (OSPAs) can sign up on this page. OSPA judges provide feedback to undergraduate, master’s, and PhD student presenters on their research and presentation skills. Greg McFarquhar, OSPA program liaison for poster session A033 and oral session A054 (Aerosol, Cloud, Precipitation, and Radiation Studies over the Southern Ocean) is seeking volunteer judges for those sessions.

Featured Field Campaign Presentations
Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC)
The massive 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 German-led 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. ARM provided the most atmospheric instruments—more than 50—to the expedition.
Matthew Shupe, a DOE-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:

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.

Cloud, Aerosol, and Complex Terrain Interactions (CACTI)
From October 2018 through April 2019, CACTI 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.
