The CNR 1 design is such that both the upward facing and the downward-facing instruments
measure the energy that is received from the whole hemisphere (180 degrees field of view). The
output is expressed in Watts per square meter. The total spectral range that is measured is roughly
from 0.3 to 42 micrometers. This spectral range covers both the Solar Radiation, 0.3 to 3
micrometers, and the Far Infrared radiation, 4.5 to 42 micrometers.
