Why I Think The TOBS Adjustment Is BS

You get your nice new Min/Max thermometer and set it up. First afternoon the temperature is 65F when you take you measurement at 4 pm and reset your thermometer. An hour later, a cold front comes through and the next day the high is 30F.

So when you go to take the reading the next day, you record that the high temperature was perhaps 63F, 33 degrees higher than the actual maximum. Only a complete idiot would not immediately recognize that as a problem, so you would start resetting your thermometer at night to prevent it from happening again.

TOBS adjustment assumes that all of the station operators are complete idiots.

    TOBS also assumes that highs and lows occur in a predictable fashion. When it comes to human observation of nature, you take what you get, unless you have an agenda.

    -Any adjustment to recorded measurements make the results invalid. These idiots want us to believe model outputs loosely based on recorded temperatures are meaningful in any way. The reported results are no better than make believe stories meant to scare little children.
    GISS admits to their deception.

      So we put them wherever and take the data at different times and as long as we get 14.2 global average everything is honky-dorey? At least when my local weather guy tells me the max and min he gives times if there is something unusual.

      I suppose after we homogenize them, we get sweeter smelling BS.

        Bob:
        Your weather man uses temperatures that are recorded at a location that is most likely not even relevant to where you live. For five years I watched temperature reports from 3 locations, 30 miles apart, and at about the same elevation. The average may have come out the same but the site experienced 10F differences in temperatures depending on the weather conditions at each site. One of the sites was my own weather station. The other two were at airports and there was no pattern in the variations except differences in weather conditions at the time of temperature being observed.
        I do not even thing the perfume they try to apply to the records can overpower the stench of decay.

  3. They are digging for ways to raise modern temps and lower historic ones. This TOBS did that, so they are using it. If it had gone the other way, they would have dropped it.

    They just want to play hockey. We need to play hard ball.

    “TOBS adjustment assumes that all of the station operators are complete idiots.” Not really. What they assume is that they can get away with it because the liberal base is full of morons that will believe what they are told. And they are right.

    Why would there be TOBS adjustments if most USHCN sites are using MMS data recorders?

      Only OBS by humans who are too safely dead to defend themselves get TOBS adjustments. Always down, because fellas back then were short, and had to look up at thermometers 2m off the ground. BION

    I’ve run analysis on the data from a couple US Climate Reference Stations. I saw that the time of day the readings were taken did offset the high and low values enough to shift the calculated average temperature as compared with readings taken at other times. As much as a 1 degree Fahrenheit difference was shown as compared to the high and low values taken from 5 minute averages. The actual difference values were unique for each of the 24 hours in a day for each of the 12 months. The results from the two USCRN stations were vaguely similar but different. How one might figure out how to apply that information to perform reliable TOBS correction to historic temperature records is beyond me. The corrections I’ve seen applied are of the same magnitude as the total temperature trend described for global warming. Those corrections are only estimates!

    I’ve been seeing “global average temperatures” stated down to the hundredth degree. Are the “official” thermometers used to obtain the raw data that precise?

    Steve, I am not sure your example works properly, “First afternoon the temperature is 65F when you take you measurement at 4 pm and reset your thermometer. An hour later, a cold front comes through and the next day the high is 30F.
    So when you go to take the reading the next day, you record that the high temperature was perhaps 63F, 33 degrees higher than the actual maximum.”

    Surely the Cold Front has not affected the MAX Reading, I thought max readings were “stored” by small Indicators on the Thermometer, as are the Min Readings.
    Now if the there was some kind of High after a day of cloud, maybe cloud cover clearing an hour after the reading was taken that could affect the Max reading.

  9. What if the daytime high is the same 3 days in a row? It happens.

    It doesn’t matter as long as the thermometer Min Max markers are reset each day after the reading is taken.

  11. Anto says:

    I still want to know why the temps are being increased each and every year. What’s going on with the thermistors that each and every year, they are recording ever cooler temperatures, such that the raw data needs to keep being adjusted upwards?

    Modern numbers go up, older numbers go down. The aim of the game is to create a slope, and the appearance of a trendline. Bogosity and Bollocks.
