Solar Zenith Angle [°]
Directional, or cosine, response is
defined as the measurement error at
a specific angle of radiation incidence.
Directional error for Apogee SU-300
series UV-I/UV-B sensors is
approximately ± 2 % and ± 5 % at solar
zenith angles of 45° and 75°,
respectively.
Mean cosine response of four
Apogee UV-I/UV-B sensors. Cosine
response was calculated as the
relative difference of UV-I/UV-B
sensors from a reference UV-I/UV-B
sensor deployed outdoors. These
data are the average of the AM and
PM response.
