This experimental study compares various methods of reducing the effects of solar radiation on outdoor air temperature measurements. It indicates that radiation effects can introduce significant measurement error, even with the use of shielding devices and aspiration, and outlines efforts that were taken to lessen the error caused by radiation.
Two separate tests were conducted, one comparing naturally ventilated and fan-aspirated radiation shields, the other comparing seven identical fan-aspirated shields. Results from the first test showed that one of the naturally ventilated shields was generally more effective than a fan- aspirated unit-at some instances of high radiation giving daytime temperatures …
