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 seven
apogee SQ-500 quantum sensors.
Cosine response measurements
were made on the rooftop of the
Apogee building in Logan, UT. Cosine
response was calculated as the
relative difference of SQ-500
quantum sensors from the mean of
replicate reference quantum sensors
(LI-COR models LI-190 and LI-190R,
Kipp & Zonen model PQS 1).
