Standardized Drought Analysis Toolbox (SDAT)

A client-side dashboard for deriving nonparametric standardized drought indices from station and gridded datasets.

The Standardized Drought Analysis Toolbox offers a generalized framework for deriving statistically comparable drought indicators without forcing a parametric distribution fit. It can be applied to precipitation, soil moisture, relative humidity, runoff, streamflow, groundwater level, surface water supply, and water storage data.
