Gumbel distribution fit parameters for historical GloFAS river discharge data (1979–2023)

For the historical GloFAS v4.0 river discharge from 1979 to (and including) 2023, the yearly maximum was calculated for every grid cell. Then, the time series of yearly maxima for every cell was used to fit a right-skewed Gumbel distribution using the method of moments. The fitted parameters were saved as "loc" and "scale" variables in a NetCDF dataset with the same grid configuration as the GloFAS historical data. Additionally, the "samples" variable was stored, indicating the number of samples used from each location to fit the respective parameters. The dataset was then compressed using "zlib" with maximum compression level.
