In 2022, Alexander R. Gottlieb and Justin S. Mankin from Dartmouth College published a commentary/data paper on the emerging topic of snow droughts. The snow droughts happen because there is decreasing snow pack, especially in the western US, under climate warming. The definitions, quantification methods, and warm-season implications of snow droughts are still unclear. The authors therefore compiled an ensemble of in situ, satellite, and reanalysis datasets in an attempt to address some of these issues.
