In May 2007, we took a look at station data for Dawson, Canada, data that is important to dendros because it goes back to the gold rush days of the late 1890s and because there are important tree ring chronologies in the area. In this case, the dendros decided that the GHCN adjusted data was […]
UPDATE – GISS LOCATIONS AND GLOBAL NIGHTLIGHTS KML DATABASE FOR GOOGLE EARTH NOW ONLINE! Thanks to data provided by Steve McIntyre and conversion skills provided by Barry Wise, we now have the first ever interactive global mapping tool for nightlight ratings and GISS stations worldwide that encompass USHCN and GHCN station locations. Download it from the surfacestations website here […]
Several recent posts and hundreds of associated comments have focused on the subject of temperature adjustments. TOBS, homogeneity, scribal records, rural versus urban … it is enough to make one’s head spin. I understand the desire to adjust data, but I often wonder if the problem is simply intractable and the adjustments we do have […]
Recently Anthony Watts noted that the Lampasas TX station was relocated in 2000 to an extremely poor location and attributed a hockey-sticking of the Lampasas series to this re-location. In a comparison that I made with nearby Blanco TX (which is the sort of comparison that USHCN says that they do), it seemed plausible that […]
First, let me thank me thank Judy Curry for inviting me to make a presentation at their seminar series and for both spending so much time and energy showing me around the department and hosting me so hospitably. I was the guest at many interesting presentations by able young scientists and at splendid lunches and […]
My post on Lampasas,TX has created quite a stir when Atmoz, a climate scientist unknown person at the University of Arizona, tried to demonstrate that the temperature spike shown in the GISS data at Lampasas, TX, was not due to the relocation next to a building and asphalt parking lot, but rather some problem with […]
Pseudonymous U of Arizona climate scientist, Atmoz, has stated that the sharp increase of surface temperatures in 2000 in Lampasas TX recently reported at Climate Audit is not due to problems resulting from site relocation, but from an unidentified faulty algorithm (“UFA”) used by NASA. Atmoz stated Adjustments made by [NASA] GISS to this station […]
The http://www.surfacestations.org project continues to collect new stations, though we could certainly use more help in the midwest, particularly Kansas, Nebraska, Oklahoma, and Texas. This NOAA USHCN climate station of record #415018 in Lampasas, TX was found to be tucked between a building, and two parking lots, one with nearby vehicles. According to the surveyor, […]
Many climate studies use an equirectangular projection, in which lines of latitude and longitude are equally spaced, to graphically summarize data. An example is the following figure from Hansen et al 1988, discussed here recently under the topic Hansen and Hot Summers: John Goetz uses the same projection in his recent thread here, Historical Station […]
Allan Macrae has posted an interesting study at ICECAP. In the study he argues that the changes in temperature (tropospheric and surface) precede the changes in atmospheric CO2 by nine months. Thus, he says, CO2 cannot be the source of the changes in temperature, because it follows those changes. Being a curious and generally disbelieving […]
