Purdue University: Shepson Atmospheric Chemistry Group: 2022 Utqiagvik Campaign

2022 Utqiagvik Campaign


From early February until mid April several researchers from Purdue, the University of Michigan, Pennsylvania State, University of Alaska-Fairbanks, and University of Albany will be doing field work in Utqiagvik, Alaska (formerly "Barrow") for CHemistry in the Arctic: Clouds, Halogens, and Aerosols (CHACHA).  This project involves flying two airplanes in coordinated flights, around the AK North Slope, out over the sea ice in the Beaufort and Chukchi Seas, and over the open water, from "leads" (large cracks) in the sea ice.  The airplanes are the University of Wyoming King Air, and the Purdue Airborne Laboratory for Atmospheric Research (ALAR). 

The project is focused on how sea salt particles get lofted into the air from various surfaces, how they influence clouds in the Arctic, and ultimately how climate change is impacting Arctic cloud cover, which is an important climate feedback in the Arctic.
