Cosine Response
Upward- and Downward-looking Two-band Sensors
Directional, or cosine, response is defined as
the measurement error at a specific angle of
radiation incidence. Error for Apogee S2
series upward-looking sensors is
approximately ± 2 % and ± 5 % at solar zenith
angles of 45° and 75°, respectively.
Upward (model S2-121)
Downward (model S2-122)
