One of the funnier claims about TOBS is that the frequency of 100 degree temperatures in the 1930’s was due to double counting at stations which reset their thermometers in the afternoon.
I put that to the test by identifying all of the stations which reset their thermometers at times other than between 2PM and 8PM on July 15, 1936, and calculating the frequency of 100 degree temperatures at those 329 stations. The result is essential identical as I get for all stations. There is no evidence of double counting. The 1930s were much hotter.

Same is true for 90 degree days. The 1930s were much hotter. No one can claim that these stations reported maximum temperatures too high due to TOBS.

Summer maximum temperatures at those same stations were much hotter in the 1930s, and have been declining for over 100 years, showing once again that the claims about TOBS strongly affecting maximum temperatures are nonsense.

At some point it will become obvious to everyone that the USHCN temperature adjustments which reverse the long term cooling trend in the US, are bogus and junk science.
Here is the station list :
