Berkeley Earth, Very Rural and Not

Jet exhaust as climate forcing Guest Post by Willis Eschenbach The good folks over at the Berkeley Earth Surface Temperature project have published their paper about urban heat islands. It’s called “Influence of Urban Heating on the Global Temperature Land Average using Rural Sites Identified from MODIS Classifications”, by Wickham et al, hereinafter W2013. They…

Station bias – an old problem

A number of readers have commented about the story from Sunday about NOAA’s experiment at Oak Ridge Laboratory to determine the warming effects of siting suggesting that the experiment was long overdue. many found it surprising that it has taken NOAA this long to get serious about the issue that Dr. Roger Pielke Sr. and…

Via experiment, NOAA establishes a fact about station siting: ‘nighttime temperatures are indeed higher closer to the laboratory’

WUWT readers may recall that I wrote about this experiment being performed at Oak Ridge national Laboratory to test the issues related to station siting that I have long written about. NOAA’s ‘Janus moment’ – while claiming ‘The American public can be confident in NOAA’s long-standing surface temperature record’, they fund an experiment to investigate…

New paper on the quality of USHCN station siting

Dr. Roger Pielke Sr. draws attention today to a new study that cites Fall et al. 2011 aka the “Surfacestations Paper” that I co-authored, which was a follow up to my original surveys published in Watts 2009. The new paper is: Martinez, C.J., Maleski, J.J., Miller, M.F, 2012: Trends in precipitation and temperature in Florida,…

Important New Paper on the Nocturnal Boundary Layer, Mixing, and Radiative Forcing as it applies to GHCN weather stations

From Dr. Roger Pielke Sr. comes word of an important new paper that shows how the air near the ground (boundary layer) is highly affected by sensitive nighttime dynamics, which show up in the Tmin of weather station data (GHCN stations in this case)  but are not captured by climate models. The paper also showed…
