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

| DOI: 10.5065/MH6E-SQ58

This historical dataset is recommended for ancillary use only and not as a primary research dataset. It has likely been superseded by a newer, improved dataset.


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NOTE: This dataset has been superseded by a newer version that is available from NCEI.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
