Welcome!

In an effort to mitigate the spread of COVID-19, all colloquia for the Fall 2020 semester will be held virtually via Zoom. We have also partnered with INSTAAR, Geology, and Geography to convene the Joint Earth Seminar Series (JESS) throughout the academic year. JESS seminars will also be held over Zoom on a monthly basis and will rotate among the aforementioned departments.


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 a virtual 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

If you would like to nominate a speaker (including yourself), please email the Chair of the ATOC Colloquium Committee, Prof. Jan Lenaerts.
