3. Installation
For measurement of the Net Radiation, it is most important that the instrument
is located in a place that is representative of the entire region that one wishes to
study.
When installed on a mast, the preferred orientation should be such that no
shadow is cast on the Net Radiometer at any time during the day. In the
