Short summary
Snow droughts can threaten water supplies, ecosystems, and communities, but studies often use different methods and data, making results hard to compare. We developed an open-source Python tool that combines snow drought detection methods, data download, mapping, and standardized output in one workflow. Tests with global snow data show that the tool identifies annual, monthly, and daily events consistently. This makes snow drought studies easier to repeat, compare, and use in planning.
