Resource Abstract:
- description: This dataset replaces the previous Time Bias Corrected Divisional Temperature-Precipitation Drought Index. The
new divisional data set (nCLIMDIV) is based on the Global Historical Climatological Network-Daily (GHCN-D) and makes use of
several improvements to the previous data set. For the input data, improvements include additional station networks, quality
assurance reviews and temperature bias adjustments. Perhaps the most extensive improvement is to the computational approach,
which now employs climatologically aided interpolation. This 5km grid based calculation nCLIMGRID helps to address topographic
and network variability. This data set is primarily used by the National Oceanic and Atmospheric Administration (NOAA) National
Climatic Data Center (NCDC) to issue State of the Climate Reports on a monthly basis. These reports summarize recent temperature
and precipitation conditions and long-term trends at a variety of spatial scales, the smallest being the climate division
level. Data at the climate division level are aggregated to compute statewide, regional and national snapshots of climate
conditions. For CONUS, the period of record is from 1895-present. Derived quantities such as Standardized precipitation Index
(SPI), Palmer Drought Indices (PDSI, PHDI, PMDI, and ZNDX) and degree days are also available for the CONUS sites. In March
2015, data for thirteen Alaskan climate divisions were added to the nCLIMDIV data set. Data for the new Alaskan climate divisions
begin in 1925 through the present and are included in all nCLIMDIV monthly updates. Alaskan climate data include the following
elements for divisional and statewide coverage: average temperature, maximum temperature (highs), minimum temperature (lows),
and precipitation. The Alaska nCLIMDIV data were created and updated using similar methodology as that for the CONUS, but
with a different approach to establishing the underlying climatology. The Alaska data are built upon the 1971-2000 PRISM averages
whereas the CONUS values utilize a base climatology derived from the nCLIMGRID data set.; abstract: This dataset replaces
