Grids of principal component gradients and varimax-rotated components 1 & 2 for the extent of the GNLCC study area saved as asciis with a 2km resolution. PC1 and RC1 represent a latitudinal gradient of temperature, while PC2 and RC2 represent a longitudinal gradient of precipitation seasonality and continentality.These grids are saved in in the Albers Equal Area Conic projection. A principal component analysis of the study area was conducted using 12 climate variables. These grids represent site scores for principal components 1 & 2. Following the PCA, variable loadings were rotated using a varimax rotation, and new rotated site scores were developed. While these rotated components are interpretable they do not...

Note: this data release has been depecrated. Find the updated version here: https://doi.org/10.5066/P9FJCM8N. The Skykomish and Snoqualmie River basins in western Washington provide spawning, rearing, and migration habitat for several salmonid species, including Endangered Species Act-listed Chinook salmon, steelhead trout, and bull trout. The production, abundance, distribution, and the health of fish and other aquatic life is strongly influenced by water temperature, which affects their physiology and behavior. The Washington State Department of Ecology establishes water temperature criteria and Total Maximum Daily Load standards for designated aquatic life uses, varying between 12 and 17.5 degrees Celsius, depending...
