ERA5 provides hourly estimates of a large number of atmospheric, land and oceanic climate variables. The data cover the Earth on a 30km grid and resolve the atmosphere using 137 levels from the surface up to a height of 80km. ERA5 includes information about uncertainties for all variables at reduced spatial and temporal resolutions.
I have converted temperature and potentially other weather variable grids to national and sub-national boundaries for use in several papers.
Available for download (see Data below) in RDS (compact) or csv (large) format.
In Python it is easy to load RDS files and much more compact files than csvs too.
