The cloud mask data was created from measurements from a mini micropulse lidar at the Chilean Antarctic Research Station, Professor Julio Escudero, on King George Island. The research platform at Escudero is supported by the Instituto Antártico Chileno (INACH). Processing to produce a cloud mask was done following Rowe et al. 2025, Observations of Clouds and Radiation Over King George Island and Implications for the Southern Ocean and Antarctica, J. Geophys. Res. Atmos.
