Quick Drought Response Index Version 6, 7 Day CONUS Composite

Quick Drought Response Index (QuickDRI) serves as a drought alarm and is designed to have improved sensitivity to early-stage drought conditions and rapidly evolving drought events. This index is calculated using similar methods to VegDRI. QuickDRI models incorporate multiple remote sensing- and climate-based input variables that portray key components of the hydrologic cycle influencing drought-related vegetation stress (for example, evapotranspiration [ET], soil moisture, and vegetation index-based plant health).
