I'm trying to reconstruct the time series of a weather station over the whole 1991-2020 period by using an external model as predictor.
I've successfully used ERA5-Land as predictor for temperature as the correlation with station data is quite high, however I'm struggling to do the same for precipitation.
What is the best alternative to reanalysis in this case? I was thinking about datasets of daily precipitation measured from satellite but the data seems to be quite coarse.
In my case I have the following requirements
You have any suggestions on which dataset I could use?
