and the concrete building 6 feet away don't store heat in the day to then to warm up the air around the instrument at night as the heat re-radiates. Upon exposure to temperature the Thermex sheet instantaneously and permanently changes color. I called out intersections as we passed them and he wrote down the times. . Another was the PRT-5, a large area radiation thermometer. Update #5: The other half of my son's project was to participate in the SurfaceStations. You can see the results. . This arrangement added a complete factory automation process controllers product line to Pyrometer.
The first night we went north (click to enlarge The second night we went south. . This is a project my son did for Science Fair to measure the urban heat island effect in Phoenix. . All commenters welcome, and I never delete comments except in the case of outright advertisement spam.
Unfortunately, I do not think this is the case - studies like this one taken at 5AM have seen the same results. . Thermometer two a few hundred kilometers away shows no warming. . Below is a picture from the ushcn station at Miami,. .

Thermex is inexpensive, precise and disposable. That way, with data taken in both directions, the results could be averaged and the cooling rate would cancel out. . My data below uses the GPS data, which was matched with the temperature data in an Excel spreadsheet using simple Vlookup calls.

In fact, I seem to see more giss corrections fixing imagined downwards biases than upwards biases. . Org survey of ushcn temperature stations. . Our specialists are available to advise you about the best products. What I said, and I think it is true, is that the ipcc does not believe urban heat islands substantially bias the surface temperature record, and, if they do, their effect can be statistically corrected by approaches like that used by the giss and discussed.
In particular, the fact that we did the run both ways tends to help us weed out the evening cooling effect as well as any progressive heating effect from the car itself. . It reminds me a lot of my kids spreading the food they don't like in a thin layer all over the plate, hoping that it will be less noticeable than when it sits in one place in a big pile.

My son used a map and a watch to mark our times, after synchronizing clocks with the data logger, so he could match times to get temperature at each location. . Both nights were cloudless with winds below 5 mph. . Update: Per some emails I have received, it is theoretically possible for the urban heat island effect to be real and to have integrity in the surface temperature record. .
