I want to use MERRA-2 model's monthly data of 500hpa geopotential height for different districts of Pakistan (1980-2019). I want to download this data from NASA Giovanni and I want to select time series area averaged option but I am confused that should I download the data in excel form or netcdf?? Can anyone guide me that getting the data directly in excel is ok or first I download netcdf files for the whole country (Pakistan) and then extract each district and convert it to excel in the last??
Thank you.
