Clean Air Happy Hour at AGU, Tues, 13 Dec, 2022 6-8 pm

RSVP HERE

The event will showcase a variety of clean air-focused organizations and initiatives working in non-profit, academic, and for-profit settings. You can learn about their missions and resources and opportunities they offer to the research community, and what they might need from researchers. And there will be plenty of time to network with the larger community passionate about working toward cleaner air. There will be complimentary appetizers and drinks.

See you there!
