Re: "Could you send the link" GHCN data is here: https://www.ncdc.noaa.gov/data-access/land-based-station-data/land-based-datasets/global-historical-climatology-network-monthly-version-4 … If you want to make map, then feel to. I have no link for a GHCNv4 map, I do, however, have a GHCN that already accounts for uncertainty from coverage: https://journals.ametsoc.org/doi/pdf/10.1175/JCLI-D-18-0094.1 …pic.twitter.com/OsnhuvwuMo
