GSL participates in the 2025 AGU Annual Meeting

The American Geophysical Union (AGU)’s Annual Meeting brings together the world’s leading Earth and space scientists. Several GSL scientists presented talks and posters at the 2025 Annual Meeting (“AGU25”) at the New Orleans Convention Center from December 15 to 19, 2025.

This year, the GSL team delivered 16 oral or poster presentations, in addition to chairing two sessions. These presentations represent a small part of the wide range of research taking place at GSL, as well as the significant contributions made by GSL affiliates from the Cooperative Institute for Research in the Atmosphere (CIRA, at Colorado State University) and the Cooperative Institute for Research in Environmental Studies (CIRES, at University of Colorado Boulder).

Below is a list of GSL’s presentations with links to each full abstract. A full, searchable list of all AGU25 presentations is available on the AGU25 Online Program.
