7th ANtarctic Gravity Wave Instrument Network (ANGWIN) Workshop & 7th Atmospheric Waves Experiment (AWE) Science Team Meeting
6–10 October 2025 – Utah State University · Logan, Utah
Atmospheric gravity waves (GWs) play a vital role in coupling the lower atmosphere with the ionosphere and thermosphere. While progress has been made in understanding their behavior, many questions remain. This joint workshop will bring together complementary research efforts to deepen our knowledge of GW generation, propagation, and impacts.
ANGWIN
The ANtarctic Gravity Wave Instrument Network (ANGWIN) is a collaborative, international effort launched in 2011. It leverages a network of ground-based instruments across Antarctica to investigate gravity waves on a continental scale. ANGWIN’s primary focus is identifying the dominant wave sources, understanding their propagation characteristics, and assessing their broader impacts across the atmosphere.
AWE
The Atmospheric Waves Experiment (AWE) is a NASA-funded mission utilizing the Advanced Mesospheric Temperature Mapper (AMTM) aboard the International Space Station since November 2023. This instrument provides near-global 2D temperature maps of the mesosphere's hydroxyl (OH) layer (~87 km altitude) every 1.1 seconds across a 600-km field of view, between ±55° latitude.
AWE's science objectives include:
- Measuring seasonal and regional variability of gravity waves near the mesopause.
- Identifying the primary mechanisms driving wave activity.
- Quantifying how these waves influence the ionosphere-thermosphere system.
