Hi,
Today (19th of April) I downloaded a NetCDF from “ERA5 hourly data on pressure levels from 1940 to present”. I noticed that the values for a variable change when I download more variables. E.g., the mean temperature of my NetCDF was 219 K when I only downloaded the temperature variable. When I downloaded the same NetCDF, but now also with geopotential, the mean became 217 K. Things got even worse when I added more variables (mean temp = 5.8e-7 K).
I am positive that I only took the mean of the temperature, inspecting the individual values of temperature confirmed that they changed too.
Could the NetCDF data still be corrupted?
Best regards,
