Short summary

Antarctic sea ice albedo is a key factor influencing the global energy balance. Here we present a daily 1 km shortwave albedo product for Antarctic sea ice from 2012 to 2021, based on Visible Infrared Imaging Radiometer Suite (VIIRS) reflectance data. The albedo for missing pixels due to cloud cover was also reconstructed. This dataset can be used to assess changes in Antarctic sea ice, radiation budget, and the strength of sea ice albedo feedback, as well as their potential interconnections.
