***
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
2
, avg. wind speed ≤ 2 mph
(1 m/s), reference: RM Young Model 43408 Fan-Aspirated Radiation Shield).
