GMAO: a Strong Presence at AMS


AMS 2023

In January 2023, representatives from NASA’s Global Modeling and Assimilation Office (GMAO) presented at the 103rd Annual Meeting of the American Meteorological Society (AMS), held in the Mile High City of Denver, Colorado. The weather was mostly mild for the duration of the conference within view of the front range of the Rocky Mountains. This year’s AMS theme was Data: Driving Science. Informing Decisions. Enriching Humanity.

As in previous recent years, AMS provided a virtual option for both presenters and attendees. GMAO presentation and poster topics ranged from the relationship between methods for estimating uncertainties in data assimilation to the global burden of tropospheric ozone.

Watching over the proceedings, and standing 40 feet tall, was the convention center’s blue bear statue, named “I See What You Mean”.
