Annual Temperature, 1981-2010 (Maximum Temperature)

Map type: Climate

The annual temperature raster layers available in the North American Environmental Atlas represent key climatological variables, including Annual Mean Temperature, Maximum Temperature of the Warmest Month, and Minimum Temperature of the Coldest Month. These datasets are based on climatological normals for the 1981–2010 reference period.

These temperature layers depict the thermal regime of North America and support a wide range of ecological, environmental, and climate-related analyses. They provide baseline climatological conditions essential for species distribution modeling, land cover interpretation, climate impact assessments, agricultural and forestry applications, and hydrological modeling.

The North American layers were derived from the CHELSA v2.1 bioclimatic variables dataset, a high-resolution global climate product developed by the Climatologies at High Resolution for the Earth’s Land Surface Areas (CHELSA) initiative hosted at the Swiss Federal Research Institute for Forest, Snow and Landscape Research WSL.
