About the ATOC Colloquium
The Department of Atmospheric and Oceanic Sciences Colloquium will be held approximately every other Friday from 11:00 AM–Noon. Come early for coffee starting at 10:45 AM, and stay after for discussions during lunch.
Colloquia will alternate between the following two formats:
A. Full-length talk by a faculty member or invited speaker
B. Three conference-length talks by graduate students or post-docs
