The 2023 American Geophysical Union (AGU) Fall Meeting will be held from December 11 to 15 in San Francisco, California, as well as online. With more than 25,000 attendees expected, the meeting might feel overwhelming. We make it easy for you to find Atmospheric System Research (ASR)-related presentations, meet up with colleagues, and discover new connections during the event.
Below is a list of ASR-related AGU meeting highlights (all times Pacific). Information is subject to change; please check the AGU Fall Meeting website for the most up-to-date information.
During the meeting, make sure to follow the Atmospheric Radiation Measurement (ARM) user facility on X (formerly Twitter) and Facebook for a real-time guide to relevant activities using the hashtags #ARMAGU and #AGU23.
Discover more, sessions, talks, and posters related to Atmospheric System Research (ASR), as well as ARM-related presentations and posters.
Add your presentation to be featured on the ASR or ARM presentation web pages.
Attending AGU in person? Make sure to visit with ASR representatives at the U.S. Department of Energy’s (DOE) Office of Science Biological and Environmental Research (BER) program booth (#414) in the AGU exhibition hall. Also, stop by the ARM booth (#614), where you can view facility materials and meet with ARM representatives.
NEW: AGU continues virtually in January: AGU will hold poster sessions and select invited panels, town halls, and workshops the week of January 20–25. All events will be online. Separate registration is required for the workshops. Check the AGU schedule for more information.
Ignite@AGU
DOE ASR Program Manager Jeff Stehr will present “Building a Career in Science with Improv Comedy” as part of Ignite@AGU on Wednesday, December 13, at 6 p.m. at the Great American Music Hall, 859 O’ Farrell Street, San Francisco.
Ignite@AGU enables scientists to showcase their professional and personal interests through fast, creative presentations. The aim is to inspire, share, and make connections—to ignite conversation. It is not your average research talk.
Agency Lecture
DOE Undersecretary for Science and Innovation Geraldine (Geri) Richmond will lead the AGU featured plenary lecture on Thursday, December 14, from 2:10 to 3:10 p.m. at Moscone Center, Room 201–202 (South, Level 2).

TRacking Aerosol Convection interactions ExpeRiment (TRACER)
The TRacking Aerosol Convection interactions ExpeRiment (TRACER), which ran from October 2021 through September 2022, provided convective cloud observations with high space and time resolution over a broad range of environmental and aerosol conditions around the Houston, Texas, region.
As part of TRACER, ARM deployed a portable observatory southeast of downtown Houston, a scanning precipitation radar south of downtown, and an ancillary site southwest of the city, where tethered balloon systems were launched. Together, these ARM measurements are helping researchers better understand the variability of aerosols and meteorology between the urban Houston area and surrounding rural environments.
