The amount of liquid and ice in clouds affects how much they warm or cool the surface in the rapidly warming Arctic. Dust aerosols cause cloud droplets to freeze and may be why clouds at similar temperatures are substantially icier over the Arctic than over the cleaner Antarctic. This data set includes data underlying the figures in Zamora and Kahn (2024), "Dust-driven cloud glaciation over summertime Arctic sea ice" (submitted). We used satellite, reanalysis, and model information to better understand how clouds containing dust were different from other clouds in similar meteorological conditions over summertime sea ice and how this might affect cloud radiative effects. We also assessed which meteorological and aerosol variables were most predictive of cloud changes associated with dust. The data from this study are taken between May to September from the years 2008-2010 and 2012-2015. This data set specifically includes information on cloud phases over sea ice between 0.6 to 8.5 kilometers (km) (fC.csv). ...
