Precipitation (1981–2010) – Monthly

Map type: Climate

The Monthly Precipitation dataset consists of 12 raster files, one for each month, representing total monthly precipitation values for the 1981–2010 reference period.

These monthly precipitation layers characterize the spatial and seasonal distribution of precipitation across North America throughout the year 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, water resource assessments, and hydrological modeling.

The North American monthly precipitation layers were derived from the CHELSA-climatologies v2.1 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 Institute for Forest, Snow and Landscape Research WSL.
