USHCN 2.5 – Estimated Data Is Warming Data – USA 1980 – 2014

sunshine hours

I’ve been posting on USHCN and the effect of “estimating” or “Infilling” on  the Final data. I did Arizona earlier.

I repeat … this is the Final data after all the other adjustments. About 15% of the data is Estimated from neighboring stations.

I will post all the monthly graphs … but just discuss the first – January.

The data is 1980 to 2014. So it has the 1980-1990 warming trend in it.

The trend of REAL data is 0.23C/decade. That’s the 35,854 values referenced in the legend.

Then they add in about 15% Estimated data with a trend of  +0.66C/decade. That’s the 4516 values.

The net result is a new trend of +0.33C/decade.

Presto. Magic. A .23C trend is now a .33C trend. (Click on graphs for larger).
