The group is hard at work finalizing all of the various data from the project, working on manuscripts, and pushing forward with the modeling component of the study.

Keenan will soon be able to spend some time working with Laurens to dive further into the model, helping us to better understand the processes controlling all of the interesting chemistry we measured within and above the snow at Summit and Toolik Lake.

Brie had the opportunity to present several different aspects of our work at both Toolik Lake and Summit to the community. In May she gave a talk presenting cutting-edge measurements of unique springtime ozone and mercury behavior at Toolik Lake, AK at the NOAA ESRL/GMD annual conference:

And in June she presented some interesting results relating to our understanding of the physics of the lower atmosphere over the Greenland ice sheet at the International Symposium for the Advancement of Boundary-Layer Remote Sensing:
