National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information (NCEI)
The U.S. Climate Divisional Dataset (nClimDiv) is derived from the nClimGrid-Monthly dataset, a long-term temporally and spatially complete dataset from 1895 to the present for the contiguous United States from NOAA's National Centers for Environmental Information. The dataset provides temperature, precipitation and drought indices, as well as heating and cooling degree days. Coverage is provided for U.S. climate divisions, states, multi-state regions, and the nation. Text output, and static and interactive graphs are available.
