Outside temperature accuracy is based on the temperature sensor itself and not on the sensor and
the passive shielding together. The solar radiation induced error for standard ration shield: +4F (2C)
at solar noon; for fan aspirated radiation shield: +0.6F (0.3C) at solar noon (insolation = 1040 W/m
