Not exact matches

After looking at 100 year long daily records of Tmin and Tmax for a bunch of sites, it seemed pretty clear to me that we could do with one measure.

http://www.drroyspencer.com/2012/04/ushcn-surface-temperatures-1973-2012-dramatic-warming-adjustments-noisy-trends/ Since NOAA encourages the use the USHCN station network as the official U.S. climate record, I have analyzed the average -LSB-(Tmax + Tmin) / 2] USHCN version 2 dataset in the same way I analyzed the CRUTem3 and International Surface Hourly (ISH) data.

The second line of evidence is how stable Tmax is, it's really flat, most years it's 0.0 something, the Tmax average of 119 million records for the world is 0.00193, so Tmax is flat, Tmin however flutters around, it's not flat and the changes are regional, they don't happen at the same time in different places, like the ocean SST's change, and the downwind surfaces detect it.

historically Tmax and Tmin were recorded.

When that is done the accurate Tmax and Tmin are recorded for the proper day and there is no step change that requires TOBs adjustment.
