Welcome!
All colloquia for the Fall2024semester willbe held in-personand virtually overZoom, when possible. Please refer to this page for the most updated schedule and information regarding the presentation format.
About the ATOC Colloquium
The Department of Atmospheric and Oceanic Sciences Colloquium will be held approximatelyevery other Friday from 11:00 AM–Noon. Come early for coffee starting at 10:45 AM, and stay after for discussions duringlunch.
Colloquia will alternate between the following two formats:
A. Full-length talk by a faculty member or invited speaker
