Compare geographic coverage, file formats and reuse terms before choosing data for your map or analysis.
Climate pages target GIS users who need spatially interpolated climate surfaces (temperature, precipitation, bioclimatic variables) rather than raw station readings.
The category spans global climate normals, high-resolution downscaled products, and reanalysis datasets suited for ecological modeling and climate impact studies.

Category FAQ
WorldClim bioclimatic variables are the most widely used for species distribution modeling. CHELSA provides a higher-accuracy alternative, especially in mountainous regions.
ERA5 is a reanalysis product providing hourly atmospheric variables from 1940 to present at ~31km resolution, while WorldClim provides long-term climate averages (normals) at up to 30 arc-second resolution.
