This workshop was recommended at the close of a 2021 ARM/ASR joint meeting breakout session on high-latitude marine clouds and uncertainties in cloud feedbacks in a warming climate. The purpose of this workshop is to foster further interactions and lay the groundwork for observation-driven modeling exercises/evaluations to be developed for community participation. All are welcome to attend. Those interested in attending should email Mandi Campbell at mandic@ou.edu to get agenda updates and the workshop’s Zoom link. The workshop will be held from 1 to 4 p.m. Eastern time on both days (September 7 and 8).
