Atmospheric Profiles, Clouds and the Evolution of Sea Ice Cover in the Beaufort and Chukchi Seas: Atmospheric Observations and Modeling as Part of the Seasonal Ice Zone Reconnaissance Surveys
The goal of this project was to examine the role of sea-ice and atmospheric interactions in the retreat of the SIZ . As sea ice retreats further , changes in lower atmospheric temperature , humidity , winds , and clouds are likely to result from changed sea ice concentrations and ocean temperatures...
