A quick look at GHCN version 4

GHCN  version 4   beta is available.  Using the GHS  population dataset the ~27000  GHCNV4 sites were filtered  to collect only rural stations.   GHS  combines two datasets,  a  10meter  built surface  satellite dataset and a human population dataset.   https://ghsl.jrc.ec.europa.eu/.    using site locations the population within 10km  of the site was extracted.  two cases were considered:  A case where rual was defined as  less than 16 people per sq km, and a case where there were less than 7 people  per sq km, this filtering led to two subsets of the  ~27K  ghcnv4 stations. One with 15K stations and a second with 12K stations.   The temperature data used was the unadjusted  monthly T Avg.

    The picture is surprisingly similar to the pictorial dynamics of grain yield in Russia. Although, no wonder, the yield is critically dependent on the climate, but it is severe in Russia.

    Hey Mosh looks like you’re having trouble naming even just one rural site which shows the urban warming trend depicted in your fake GHCNv4 chart.

    I’m not surprised …

    Your chart is likely for rural sites which have been corruptly adjusted to match urban warming.

    I’m aware of numerous rurla sites which have been thus adjusted.
