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)
