Temperature and precipitation values are provided for over 3,800 communities throughout Alaska and Western Canada for each of the following date ranges:

Historical (1961 - 1990)

2030 - 2039

2060 - 2069

2090 - 2099

Each mean temperature and precipitation value in the CSV is an average of single pixel data extractions from raster data over the corresponding date range. Min/max temperature values are taken from the years with the minimum and maximum values over the corresponding date range.

The following raster data sets were used:

Historical Monthly Temperature Products - 10 min CRU TS 3.22

Historical Monthly Precipitation Products - 10 min CRU TS 3.22

PRISM 1961-1990 Climatologies

Projected Monthly and Derived Temperature Products - 2km CMIP5/AR5

Projected Monthly and Derived Precipitation Products - 2km CMIP5/AR5

Projected Monthly Temperature Products - 10 min CMIP5/AR5

Projected Monthly Precipitation Products - 10 min CMIP5/AR5

The PRISM dataset is used as the historical baseline for each location except Northwest Territories locations. 2km projected data is used for these locations to match the resolution of the PRISM dataset.

Northwest Territories are not included in the PRISM data, so these locations use the CRU TS 3.22 dataset for their historical baseline. 10min projected data is used for these locations to match the resolution of the CRU TS 3.22 dataset.

Projected data are based on our 5-model average downscaled AR5 temperature and precipitation products.
