I wonder if the claims that 2012 was the hottest year ever in the US is up for a downgrade?Dispatch from AMS: Looking at Land Surface Temperatures
Friday, January 18, 2013
One, by John Kochendorfer of NOAA at Oak Ridge, Tennessee, is a direct test of the importance of siting. They’ve installed four temperature sensors at varying distances across a field from the laboratory complex. The experiment has only been running since October, but already they’ve found out a couple of interesting things. First, the nighttime temperatures are indeed higher closer to the laboratory. Second, this is true whether the wind is blowing toward or away from the laboratory.
. . .
Differences between the reanalysis temperature trends and conventional temperature trends varied from place to place. In the United States, the reanalysis had widespread cooling, in contrast to the observed slight cooling in the Southeast and warming elsewhere. Do the United States temperatures have a warm trend bias, or is this a flaw in the model’s simulation of land surface weather patterns? Time, and further investigation, will tell.
