The Quick Drought Response Index (QuickDRI) is a shorter-term indicator of dryness. 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.
Groundwater and soil moisture drought indicators are generated weekly based on terrestrial water storage observations derived from GRACE-FO satellite data and integrated with other observations, using a sophisticated numerical model of land surface water and energy processes.
Produced every two weeks, the maps provide regional to sub-county scale information about drought’s effects on vegetation, integrating satellite-based observations of vegetation conditions, climate data, and other biophysical information such as land cover/land use type, soil characteristics, and ecological setting.
