I thought I would compare TAVG data from the new BEST release to the NOAA data for the state of Alabama.
I got the BEST data here. I got the NOAA data here. The BEST anomalies are as of 1951 to 1980. So I calculated the NOAA anomalies for Alabama using the same time frame. Then I convert NOAA anomalies from Fahrenheit to Celsius.
So, for example, 1950 and 2010 (temperatures are anomalies from the 1951-1980 average):

Hmmm. They don’t look too similar. So I double checked. 16 for Jan 1950? Yes, Jan 1950 was the warmest January in Alabama history according to the NOAA. It averaged 60F, which is 16F above the 1951-1980 average.
So, lets graph BEST minus NOAA_C. Whaaatttt! No wonder BEST can claim warming occurred after 1960.
They cooled all the pre-1960 data and warmed all the post-1960 data (compared to NOAA)!!
