Bernie has collated the population of the Brazil GHCN stations (used in GISS) located here. OF 20 GHCN/GISS “rural” stations, only 3 currently have populations under 5,000 and some are now cities. Of 7 GHCN/GISS “small” towns, 6 are currently cities.
I’ve loaded R-tables for the dset=1 and dset=2 versions. The R-tables are lists each 7364 long, each item is a station time series. The files are about 8 MB in size. I have a variety of little scripts to retrieve and analyze things. The data is located here: http://data.climateaudit.org/data/giss/giss.dset1.tab http://data.climateaudit.org/data/giss/giss.adj.tab Each file can be downloaded […]
Here’s something interesting: I’ve collated the GISS raw(dset=1) and GISS adjusted (dset=2) versions and then calculated the range of adjustments. The largest positive adjustment was over 8 deg C and the largest negative adjustment is greater than -6 deg C. I separated out the stations that had no adjustments (max adjustments under 0.01 deg C […]
I’ve spent some time (an inordinate amount of time) trying to figure out why GISS uses some GHCN stations and not others. Doing so has required a lot of work on GISS data sets which are nastily organized and with many seemingly ad hoc inclusions, exclusions and sloppinesses. Does any of this matter to world […]
In the discussion of the Tucson weather station, Ben Herman of the U of Arizona observed that there were serious biases with the HO-83 hygrothermometer – introduced in the early 1990s – which was said to be a contributor to the uptick to Tucson values. Although USHCN has implemented adjustments to U.S. data to deal […]
Here’s a discussion of replication policy posted up in the relatively early days of the blog, which I’ve re-posted in light of NASA spokesman Gavin Schmidt’s attempts to justify Hansen’s refusal to provide the source code used in his temperature calculations. It seems that these calculations are important enough to prompt a concern over the […]
Hansen has followed up his “Lights Out Upstairs” outburst with another outburst dismissing critics as “court jesters” with whom he will have no truck. (Lights Out is now cited on the NASA website.) His new jeremiad re-iterated the position of NASA spokesman Gavin Schmidt that U.S. errors “didn’t matter” because the U.S. was only 2% […]
NASA spokesmen Gavin Schmidt and James Hansen have observed that the US accounts for only 2% of the earth’s surface and conclude that problems in the US network don’t matter. There are only 6 Brazil stations in GHCN which have records extending through the 1930s and as late as 2004, which is an indication of […]
The NOAA website http://mi3.ncdc.noaa.gov/mi3qry/search.cfm? has a Map tab linking to local maps and Google Earth. I don’t recall seeing it before. Maybe someone can comment on this and also check the accuracy of the maps for stations shown there. I was looking to see if their equipment reporting included whether stations had aspirated or unaspirated […]
During the past 2 months, there has been an active discussion in the blogosphere about the quality of the Tucson U of Arizona weather station. While I have never claimed that the blogosphere is a substitute for academic journals, the thread of Tucson discussions seems to me to be a good example of internet discussion […]
