The Quick Drought Response Index (QuickDRI) is a shorter-term indicator of dryness. It is calculated through the analysis of satellite- and model-based observations of conditions that influence drought.
QuickDRI is a composite index that combines: Station-based precipitation, Soil moisture, Evapotranspiration, Vegetation health, and Environmental landscape characteristics, such as soils, land use, land cover, and elevation.
QuickDRI is designed to provide a snapshot of anomalously dry or wet conditions over the past 4 weeks and serves as an indicator of emerging or rapidly changing drought conditions. The maps are updated weekly over the continental United States and have a 1-kilometer spatial resolution.
