Hi! I am not sure about the resolution you are looking for. Maybe you know this, but you can download several future scenarios at 1km2 in chelsa( https://chelsa-climate.org/future/) and worclim (https://worldclim.org/data/index.html#google_vignette), please carefully read the information/descriptions of the layers. Best, Javier.
Hello Hamideh, you can get good precipitation and temperature values from University of East Anglia, a little older now but still valid. They have multiple GCM datasets, and one is from CSIRO as well, which might interest you. Further downscaling can be achieved a few ways, such as I did here Article One approach for downscaling climate change data towards reg...
Yeah, this is the modeled data. You know precipitation is highly variable in space and time, the scenario of climate change you consider, impacts the future precipitation.
