Cosine Response 

 

Directional (cosine) response is defined as the 
measurement error at a specific angle of radiation 
incidence. Error for Apogee MQ-500 series 
quantum sensors is approximately ± 2 % and ± 5 % 
at solar zenith angles of 45° and 75°, respectively.  

 

Mean directional (cosine) response of 
seven apogee MQ-500 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 MQ-500 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. 

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).
