Description

Drought is a sustained imbalance of supply (precipitation) and demand (i.e. evaporative demand). Droughts can be caused by several factors, some natural, some anthropogenic. There are numerous types of drought that can occur at different time scales – meteorological drought, agricultural drought, hydrologic drought, snow drought, and socioeconomic drought.

Climate Engine generates and provides ready access to dozens of different drought products at global scales, and that are place-based. Some of the more common drought indices include: Palmer Drought Severity Index (PDSI), Standardized Precipitation Index (SPI), Standardized Precipitation Evapotranspiration Index (SPEI), Evaporative Demand Drought Index (EDDI), Evaporative Stress Index (ESI), U.S. Drought Monitor (USDM), North America Drought Monitor (NADM), and satellite-based anomalies such as Land Surface Temperature (LST) anomalies, and Landsat vegetation and water index anomalies.
