Cosine Response
Directional, or cosine, response is defined as the measurement
error at a specific angle of radiation incidence. Error for Apogee
SQ series quantum sensors is approximately ± 2 % and ± 5 % at
solar zenith angles of 45° and 75°, respectively.
Mean cosine response of twenty-three SQ
series quantum sensors (error bars
represent two standard deviations above
and below mean). Cosine response
measurements were made by direct side-
by-side comparison to the mean of four
reference thermopile pyranometers, with
solar zenith angle-dependent factors
applied to convert total shortwave
radiation to PPFD. Blue points represent
the AM response and red points represent
the PM response.
