This is a very basic concept. The mass of the parking lot is BLACK, which absorbs more energy from the sun creating a higher temperature above it. Thermometers in close proximity develop what is called "sensor bias" because the near area air temperature is artificially increased by the asphalts warming of it.Explain the science behind asphalt then. Put up or shut up.Finally figure the rabbit whole you were going down and decide to shut up?Obtuse?
Who shut up ?
The main problem of the HCN (Historical Climate Network) is due to changes around many of the sensor sites where data is collected. This is known by scientists as the Urban Heat Island Effect or UHI. This develops around cities where most of our climatic stations are located. This is the reason US-CRN was created. to remove this artificial, man made-land use change, bias from the data.
We know, by empirical experiment, if there are enough sensors affected the combined aggregate temperature will be artificially raised.
Wow you must have a college education..
