A Tale Of Two BOM Airports

The airport at Canberra shows 1.3C/century warming since 1955, while the airport at Broome shows no warming during the same period.

The Broome thermometer is a well sited thermometer, far away from any asphalt.

By contrast, the Canberra thermometer is located next to a huge mass of asphalt and concrete. Experts at the BOM say that the warming is due to 0.0001 mole fraction CO2 added to the atmosphere over the past 100 years.

    Yes, they place these where it is the most urban heat.

    Most Excellent.. Concise and Visually to the point, a picture is worth a thousand words

    I had a similar comparison of two close together weather stations. One showed the Atlantic Multidecadal Oscillation (city) and the other showed a linear increase of the temp (airport.) Unfortunately I did not know enough to take a screen shot of the two graphs.

    I posted this at WUWT on July 3, 2010 :

    The city is on the North Carolina/Virgina border and right on the ocean. Take a look at the city vs the airport. Norfolk City and

    Norfolk International Airport

    Now we get:

    Due to technical problems with the GISS webserver, some interactive content, such as creating scientific plots using web forms, is disabled.

    That has been up for almost a year.

    The way the scientific process works is that the theory has to work for all data. Any piece of data that does not fit the theory; invalidates the theory. With the Broome Airport temperature data we have disproven the AGW theory. Case closed, move on.

    Asphalt and concrete are two items that are often used in creating heat storage in passive solar buildings…and these morons expect us to believe that putting a parking lot next to a weather monitoring station is not going to have any effect?

      +1
      I forgot that fact.

        And to make it worse…it’s the same groups/idiots that promote passive solar heating for the masses…of course, THEY won’t build a passive solar house, or at least one with several backup HVA/C systems.

    The Canberra AP AWS was moved away from the car park by 6 May 2011 to an area closer to Runway 30 and well away from asphalted areas. Now the car park has been extended to cover the area previously occupied by the AWS. I have aerial photos clearly showing this.
