WorldClim is a set of global climate layers (gridded climate data) with a spatial resolution of about 1 km2. These data can be used for mapping and spatial modeling.

Hello Mortreza,

It depends on the scale and the desired resolution of the data.

On a global scale, the Copernicus database is very useful for climate data.

Just as Dennis Becker has explained, which also depends on what you want and the purpose for which you need the data.

You may also consider the hybrid data that combine different data sources like; https://www.chc.ucsb.edu/data/chirps

You can take a look Climate Change Knowledge Portal by Worldbank. Hopefully it gives some insights.
