Time Bias Corrected U.S. Divisional Temperature-Precipitation-Drought Index, 1895 to 1993

This dataset from NCDC (DSI 9640) contains monthly average temperature, precipitation, and Palmer Drought Indices: drought severity (PDSI), hydrological drought (PHDI), Z index, and modified drought severity (PMDI), for each climatic division in the 48 contiguous U.S. states, as well as Puerto Rico and the Virgin Islands. The period of record is January 1895 to April 1993. Monthly averages within a climatic division have been calculated by giving equal weight to stations reporting both temperature and precipitation.NOTE: This dataset has been superseded by a newer version that is available from NCEI [http://www1.ncdc.noaa.gov/pub/data/cirs].
