Description

Climate Prediction Center (CPC) Palmer Drought Severity and Crop Moisture Indices are computed for the 344 U.S. Climate Divisions on a weekly basis based on a minimum of the previous 4 weeks (1 month) of observed temperatures and precipitation. Each climate division record includes a weekly averaged atmospheric temperature, precipitation, soil moisture in the upper and lower layers, percentage of flood capacity, potential evaporation, runoff, crop moisture and change from previous week, monthly moisture anomaly, preliminary or final Palmer Drought Severity Index (PDSI), and precipitation needed to end drought value. The CPC preliminary data are collected in near real-time from ground stations throughout the U.S., and are displayed in tabular form. The preliminary values are replaced by quality controlled data from the National Climatic Data Center with an approximate time lag of 3 to 6 months.
