For Detroit Lakes MN, this introduced an error of 0.8 deg C. I’ve collated GISS raw minus USHCN adjusted for all USHCN […]
I did plots for both GISS station data and GISS gridcell data on the same basis as USHCN.

Little did they know that some lost civilizations report their weather to UCAR, including the mysterious country of Chile whose existence has long been suspected. Here at last is conclusive evidence that the lost country of Chile exists, […]
