Cosine Response:

Directional, or cosine, response is defined

as the measurement error at a specific

angle of radiation incidence. Error for

Apogee SQ series quantum sensors is

approximately ± 2 % and ± 5 % at solar

zenith angles of 45° and 75°, respectively.

Mean cosine response of twenty-three SQ

series quantum sensors (

represent two standard deviations above

and below mean

measurements were made by direct side-

by-side comparison to the mean of four

reference thermopile pyranometers, with

solar zenith angle-dependent factors

applied to convert total shortwave

radiation to PPF. Blue points represent the

AM response and red points represent the

PM response.
