The most popular radiosonde manufacturer worldwide today is the Vaisala corporation, whose strategy for coping with solar heating is to concede that it will happen and try to correct for it: the thermistor is mounted on a «boom» that sticks into the air flow where the sun can shine on it, but the heating error is estimated from the measured ascent rate and solar zenith angle and subtracted from the reported temperature.
The measured transmittance (derived from the MFRSR measurements and the Langley VAP), liquid water path, and solar zenith angle and an assumed surface albedo are input to the algorithm.
A look - up table of total transmittance at 415 nm is calculated using a radiative transfer model for a range of cloud water path, effective radius, optical depth, and solar zenith angles.
The red spectral albedo generally increases with solar zenith angle, as has been noted in ground measurements of broadband albedo.
Radiation Amplification Factor (RAF); solar zenith angle (SZA); Dobson Unit (DU); ultraviolet (UV); ultraviolet radiation (UVR); cloudiness
During summer, when there's sunlight in the Arctic, the zenith angle for the incoming solar energy is quite large.
The prediction is for a roughly sinusoidal seasonal temperature cycle, based on solar zenith angle.
