Identify and Characterize Drought Events from Drought Index Time Series // Detects, describes, and analyzes drought events from time series of drought indices, such as the Standardized Precipitation-Evapotranspiration Index (SPEI). Identifies drought episodes based on threshold values and calculates their duration, intensity, severity, and peak month. Includes utilities for summarizing and visualizing drought dynamics over time. The Standardized Precipitation-Evapotranspiration Index is described in Vicente-Serrano et al.
