CEDAR email: Joint ANGWIN/AWE meeting

[Dominique Pautet]

This is the second announcement for the joint ANGWIN/AWE meeting hosted by
Utah State University in Logan, Utah, on Oct 6-10, 2025.
Registration is now open.
More information about the meeting can be accessed on the AWE website:

Meeting description:
Modern theory and modeling indicate that atmospheric gravity waves (GWs)
play an important role in the vertical coupling of the
atmosphere-ionosphere system. However, their sources, variability, and
influences are still major unknowns. This combined workshop will bring
together two complementary projects designed to better understand GW
generation, propagation, and effects:
• The ANtarctic Gravity Wave Instrument Network (ANGWIN) is a highly
successful international grassroots program that was started in 2011.
ANGWIN takes advantage of the network of instrumentation operating at
several research stations covering Antarctica, with the primary research
goal of quantifying and understanding the dominant sources, propagation and
impact of a broad spectrum of GWs on a continental-wide scale.
• The Atmospheric Waves Experiment (AWE) is a NASA-funded mission operating
an Advanced Mesospheric Temperature Mapper (AMTM) imager on the
International Space Station since November 2023. This instrument maps the
nighttime mesospheric temperature at the altitude of the hydroxyl (OH)
layer (~87 km), providing 2D GW fields over a 600-km field-of-view, every
1.1 second, and with a 2x2 km resolution, between +/- 55° latitude. In
addition, four state-of-the-art models help to address three science
objectives: (1) Quantifying the seasonal and regional variabilities and
influences of GWs near the mesopause, (2) Identifying the dominant
dynamical processes controlling GWs observed near the mesopause, (3)
Estimating the wider role of GWs in the Ionosphere/Thermosphere system.
The ambition of this meeting is to provide a venue for discussions and
collaborations between scientists involved in studying GWs and associated
mechanisms. The intention is to have contributions from recent satellite
missions, ground-based airglow, lidar, and radar observations, theory, and
atmospheric modelling.
We are looking forward to seeing you and hearing of your new results!
