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. Alaskan climate data include the following elements for divisional and statewide coverage: average temperature, maximum temperature (highs), minimum temperature (lows), and precipitation. Data for the new Alaskan climate divisions begin in 1925 through the present and are included in all monthly updates. In March 2015, data for thirteen Alaskan climate divisions were added to the NClimDiv data set. 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. For CONUS, the period of record is from 1895-present. Data at the climate division level are aggregated to compute statewide, regional and national snapshots of climate conditions. 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. 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. This 5km grid based calculation nCLIMGRID helps to address topographic and network variability. Perhaps the most extensive improvement is to the computational approach, which now employs climatologically aided interpolation. For the input data, improvements include additional station networks, quality assurance reviews and temperature bias adjustments. 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. This dataset replaces the previous Time Bias Corrected Divisional Temperature-Precipitation Drought Index.
