I recently made a trip into Oregon to survey several USHCN stations there, including Klamath Falls, Crater Lake, Bly, and Lakeview. I also made a stop at another remote USHCN…
USHCN in the "ass end of nowhere"
There’s a USHCN station out there, in the “ass end of nowhere”. Apologist Eli Rabett (Joshua Halpern) recently lamented that in order for dendrochronologists to update tree ring studies used…
California USHCN Survey – three to go
After getting some very remote and elusive stations in the past two weeks, I’m left with just three stations to go in California for my www.surfacestations.org project: Blythe, Brawley, and Santa…
Test Run in Indy
Yesterday I spent most of the day on the 51st floor (830 feet up) of the Chase Bank building (see arrow) configuring an automated Weather Channel display system. You can see…
Surfacestations.org News
California nearing completion for USHCN surveys. There are a number of surveys in the que that will soon be online, bringing California’s USHCN network to within half a dozen (or…
Road kit
I just finished testing and putting together my road kit, as seen above. Can anyone guess what it is for? UPDATE: Ok I think I have enough guesses. “Coyote” nailed…
How Not to Measure Temperature, Part 33
Until now, most of the surface temperature measurement stations I’ve highlighted as substandard locations for measuring temperature accurately have been in the USA. Today, courtesy of Geoff Sherrington, we are treated…
USHCN Station Surveys – Completion by State
www.surfacestations.org volunteer Gary Boden has provided me an updated version of the Excel speadsheet I use to chart this project. This version calculates the completion of USHCN surveys by state,…
Surfacestations.org updated, now at 800 mark
With 421 stations surveyed, we now stand at 800 stations remaining to be surveyed. The rate of surveying slowed during the month of September, which is to be expected as…
How not to measure temperature, part 32
A common theme with official climate stations of record is their placement with city and county fire stations. The reason? An observer is needed to transfer the data from the…

It’s been awhile since I updated this series, and its not for lack of material. But I got busy with the UCAR conference, publishing a slide show, and other things.…
Specs on weather stations
There’s been some discussion about specs on siting of weather stations and temperature measurement. Coincidentally, I’ve been conversing with Jos de Laat of KNMI, the Dutch Meteorological Institute who offered…
