The Keetch-Byram Drought Index (KBDI) assesses the likelihood of wildfires becoming large and difficult to contain by representing the net effect of evapotranspiration and precipitation in producing cumulative moisture deficiency in deep duff and upper soil layers. 

The Landscape Evaporative Response Index (LERI) is an experimental drought monitoring and early warning guidance tool that measures the anomaly in the actual evapotranspiration (ETa) from the land surface. This web page provides LERI plots based on accumulated 8-day, monthly, seasonal, growing season, and annual ETa for the contiguous United States and northern Mexico at a 1-km spatial resolution. 

The Lawn and Garden Moisture Index measures the capacity of current soil moisture to sustain healthy lawns and gardens in the Southeast U.S. 

NASA’s Short-term Prediction and Transition Center – Land Information System (SPoRT-LIS) provides high-resolution (about 3-km) gridded soil moisture products in real-time to support regional and local modeling and improve situational awareness.
