U.S. Climate Divisional Dataset (Version Superseded)
TCDD
This data has been superseded by a newer version of the dataset. Please refer to NOAA's Climate Divisional Database for more information. The U.S. Climate Divisional Dataset provides data access to current U.S. temperature, precipitation and drought indeces. Divisional indices included are: Precipitation Index, Palmer Drought Severity Index, Palmer Hydrological Drought Index, Modified Palmer Drought Severity Index, Temperature, Palmer Z Index, Cooling Degree Days, Heating Degree Days, 1-Month Standardized Precipitation Index (SPI), 2-Month (SPI), 3-Month (SPI), 6-Month (SPI),12-Month (SPI) and the 24-Month (SPI). All of these Indices, except for the SPI, are available for Regional, State and National views as well. There are 344 climate divisions in the CONUS. For each climate division, monthly station temperature and precipitation values are computed from the daily observations. The divisional values are weighted by area to compute statewide values and the statewide values are weighted by area to compute regional values. The indices were computed using daily station data from 1895 to present.

Purpose | The U.S. Climate Divisional Dataset is the only long-term temporally and spatially complete dataset from 1895 to the present for the contiguous United States (CONUS) from NCDC. USCDD has been used for many decades to compute long term temperature, precipitation, and drought indices. The spatial coverage was from the divisional level up to the national level. The indices were computed using daily station data from 1895 to present. |
