Brazil GHCN Station Population

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.

    So the urban heating effect maybe causing a substantial upward basis in the climate studies?

    The UHI deal has frustrated me for a while. I have been trying to find an animation of land surface temperatures after night fall which should be cool as heck to watch and a better way of defining rural areas in my opinion. I haven’t found it yet, but I know a lot of third world cities don’t have a great street light budget.

    Its beyond my ability to do so but couldn’t someone use google earth and image analysis tools to automatically determine the amount of urbanization at any given site?

    It might make a good student project.

    Terry,
    Most population density maps I am aware of do not have the level of granularity that would distinguih truly rural sites. In addition, I think micro-site effects are even more problematic in rural sites and these also need to be tracked. This Brazil data, IMO, points out that (a) the growth of these towns and cities could be a legitimate source of an increasing temp. trend and, therefore, needs to be excluded before major pronouncements on AGW and (b) the failure to quality control the data extends to areas that are trivial to maintain which bodes ill for those aspects of he data that need more comlex modes of maintenance. The Brazil data simplreinforces the main significance of the recent discontinuity Steve identified.

    There was a period before 9-11-2001 when the US gov’t was selling satellite recon photos for personal interest and archaelogical or other purposes. I remember seeing photos in National Geographic that were outside the visual spectrum. I wonder if the US gov’t would still sell relatively recent low-res IR satellite photos of sites outside the US and Iraq.

    You dont need a spy satellite to see images of the earth. NASA has Landsat and SEAsat, the ESA has Earthnet. The Russians, Chinese and Canadians also have remote sensor satellites for resource management and weather prediction. There are many sources of satellite images.

    I doubt very much that the US government would ever sell images from its network of spy satellites, as it wishes to keep the capabilities of these satellites secret, they will sequester those images as long as the satellite that produced them is in service.

    In 1997, I got the monthly mean temperature data that CRU uses in its temperature reconstruction. The stations for Brazil are listed below. 19611980, for example, means the data starts in 1961 and ends in 1980. There may be missing months or years between the start and end dates.

    And the number just before the name is the height in meters above sea level. -999 indicates missing data. Sorry about the poor formating.
