NASA's GMAO Shows Strong Presence at AGU Fall 2018 in Washington, DC

AGU meeting venue

NASA’s Global Modeling and Assimilation Office (GMAO) had a strong participation in the 2018 American Geophysical Union (AGU) Fall Meeting held in Washington, DC, from December 10th through the 14th. GMAO scientists presented their science as part of speaker panels as well as led poster sessions on topics ranging from Arctic ice to Mt. Pinatubo. Below is a list of the GMAO presenters, along with the titles of their presentations and posters.
