Pre-processed input data for large-scale High Mountain Asia snow model

Input datasets necessary to run the snow model of Kraaijenbrink et al. (2021) for the High Mountain Asia region in the same setup as the study. For more information on this data, pre-processing and the exact source datasets used, please refer to the original paper and its methods section. Model code is available here.
