Short summary

Any radiometer at a fixed location has a biased view when observing a convoluted, three-dimensional urban canopy. The bias of various sensor views (nadir, oblique, hemispherical) is quantified. The error in inferring surface temperatures ranged between -2.6 and +2.9K relative to the complete surface temperature. For a hemispherical pyrgeometer, it was found that above 3.5 times the mean building height the horizontal positional error is less than the typical accuracy of such sensors.
