7th ANGWIN workshop in Logan, Utah, USA, 06.-10. October 2025

Participants of the 7th ANGWIN workshop in Logan on 6-10 October 2025.

ANGWIN, short for ANtarctic Gravity Wave Instrument Network, is an international consortium of scientists dedicated to investigating gravity waves in the middle atmosphere over Antarctica. Originally, the “I” in ANGWIN referred to “imager”, reflecting the network’s initial focus on optical imaging instruments. However, the network has since expanded to include a broader range of observational tools, such as lidar and radar systems, enabling a more comprehensive study of atmospheric dynamics.

This year’s workshop was particularly significant because it was held jointly with the 8th Atmospheric Wave Experiment (AWE) Meeting. AWE involves an Advanced Mesospheric Temperature Mapper (AMTM) mounted on the International Space Station (ISS), which allows us to observe gravity waves in the mesosphere and lower thermosphere (MLT) on a global scale.

During the workshop, I gave two talks: first, on my study on the observation of mountain waves and secondary gravity waves in the MLT over Patagonia, which is currently under review at JGR; and second, on my newly developed algorithm designed to decompose a 3-D wave field into individual wave packets. Both presentations were well received by the scientific community, sparking engaging discussions and potential collaborations for future research.
