BEST minus NOAA – WOW – BEST has cooled the pre-1960 data and warmed the post-1960 data for Alabama

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):

Year Month NOAA_F NOAA_C BEST_C BEST minus NOAA

1381 2010.00 1.00 -4.50 -2.50 -2.54 -0.04
1385 2010.00 2.00 -7.30 -4.06 -4.13 -0.08
1386 2010.00 3.00 -3.60 -2.00 -1.59 0.41
1387 2010.00 4.00 0.70 0.39 1.28 0.89
1388 2010.00 5.00 2.80 1.56 1.77 0.22
1389 2010.00 6.00 3.80 2.11 2.52 0.41
1390 2010.00 7.00 3.00 1.67 1.82 0.15
1391 2010.00 8.00 4.10 2.28 2.51 0.23
1392 2010.00 9.00 2.80 1.56 2.15 0.59
1382 2010.00 10.00 1.30 0.72 0.65 -0.07
1383 2010.00 11.00 2.30 1.28 1.44 0.16
1384 2010.00 12.00 -6.40 -3.56 -2.98 0.58

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)!!
