Long-term Climate Normals for Alaska

Annual Average Maximum Temperature for Alaska

30-year annual average maximum temperature for Alaska at 60-m resolution for (a) the last glacial maximum period ~18,000 years ago and (b) the modern period 1975-2005.

Climate Normals for Last Glacial Maximum and Modern (1975-2005), Alaska

This dataset provides two 30-year climate normal data products for conditions during the last glacial maximum (LGM; ~18,000 years ago) and a modern time period (1975-2005) for the entire state of Alaska. One set of products includes monthly climate variable averages at 60 m resolution. The second set of products includes annual summary climate variable averages for the same variables at multiple resolutions.

The monthly averages were derived by topographically downscaling climate variables from existing coarse-resolution general circulation model outputs combined with local weather station data and digital surface models for Alaska. The annual averages are coarser-resolution upsampled versions of the 60 m resolution monthly average data. These climate normal data products were used to evaluate changes in climate across Alaska over the two time periods and to assess how results might depend on the spatial resolution of the input data products.
