NASA studies Arctic sea ice melt to improve climate models

NASA's Arctic Radiation Cloud Aerosol Surface Interaction Experiment (ARCSIX) mission is studying summer sea ice melt over the Arctic Ocean, focusing on the impact of changing ice and atmospheric conditions on global climate. The mission involves flights over Greenland, collecting data on sea ice, clouds, and aerosols. Initial findings include unexpected layers of aerosol particles and a phenomenon dubbed "sea ice sandwich." The research aims to enhance climate modeling and understanding of Arctic changes.
