WorldClim

WorldClim is a prominent global climate data repository offering free access to historical and future climate data. It provides essential variables such as monthly mean temperature, precipitation, solar radiation, relative humidity, and wind speed, alongside a set of bioclimatic variables derived from these core measurements.

This platform is widely utilized by scientists, educators, and organizations for environmental research, ecological modeling, conservation planning, and agricultural studies. The datasets are available at various spatial resolutions, making them adaptable for studies ranging from regional to global scales.

In addition to climate data, WorldClim also offers digital elevation models (DEMs), which are crucial for many geospatial analyses. The data can be downloaded directly, supporting a wide array of applications in climate change impact assessment, biodiversity analysis, and geographic information systems.
