Does there exist a global dataset on rainfall (at least 0.5x0.5 degrees grid) already in .csv or similar format?
I have found this: https://precip.gsfc.nasa.gov/
the precision is 1x1 log-lat grid. I check if it is enough for my case.
EDIT: I see that asking about rainfall data is quite common. As soon as I write the code to properly open the binary files in the link above I will share it in order that order researcher will be able to easily use these data for whatever purpose they will to. The code will be R based.
