Supergroup

This page serves as the schedule for the Atmospheric Chemistry Supergroup meetings. The shorcut is http://tinyurl.com/ac-supergroup

The format of these meetings is:

2x 1/2 hr presentations of research from two different people
Followed by happy hour on the Hill with anyone interested
The presenters are volunteers, but we strive to have representation from all the groups in CU Atmos Chem.
If you have suggestions for the organization, or are interested in presenting, please contact Jose or Anne.
