Cosine Response
Directional, or cosine, response is defined as the
measurement error at a specific angle of radiation
incidence. Error for Apogee SQ-600 series ePAR Sensor is
approximately ± 2 % and ± 5 % at solar zenith angles of 45°
and 75°, respectively.
Mean directional (cosine) response
of seven Apogee series quantum
sensors. Directional response
measurements were made on the
rooftop of the Apogee building in
Logan, Utah. Directional response
was calculated as the relative
difference of quantum sensors from
the mean of replicate reference
quantum sensors (LI-COR models LI-
190 and LI-190R, Kipp & Zonen
model PQS 1). Data were also
collected in the laboratory using a
reference lamp and positioning the
sensor at varying angles.
