The Palmer drought index, sometimes called the Palmer drought severity index (PDSI), is a regional drought index commonly used for monitoring drought events and studying areal extent and severity of drought episodes. [1] The index uses precipitation and temperature data to study moisture supply and demand using a simple water balance model.
The GPCC drought index provides SPEI datasets at a 1.0° spatial resolution for limited timescales (1, 3, 6, 9, 12, 24, and 48 months). [5] Inputs to SPEI datasets can include high-resolution potential evapotranspiration (PET) from the Global Land Evaporation Amsterdam Model (GLEAM) and hourly Potential Evapotranspiration (hPET). GLEAM is a set ...

The United States Drought Monitor is a collection of measures that allows experts to assess droughts in the United States.The monitor is not an agency but a partnership between the National Drought Mitigation Center at the University of Nebraska-Lincoln, the United States Department of Agriculture, and the National Oceanic and Atmospheric Administration.
In late 2007, NIDIS launched the U.S. Drought Portal, or drought.gov, a website that pulls together many federal, state, and academic resources for monitoring drought. [9] [10] In January 2021, NIDIS worked with NOAA's National Centers for Environmental Information to launch a completed redesigned U.S. Drought Portal. The new website features ...
