used for measuring incoming (solar) radiation should be located with an
unrestricted view of the sky in all directions during all seasons, with the
lowest solar elevation angle possible. Sensor height is not critical for
pyranometers. A tall platform or rooftop is a desirable location .
Net radiometers should be mounted about 1 m above the ground .
should be located to avoid obstructions casting a shadow on the sensor at any time. Also, light colored walls and
artificial sources of radiation should be avoided . Net
radiometers should also be located to avoid obstructions to the field of
view both upward and downward .
radiation measurements should be taken in open areas free of obstructions.
The ground cover under a net radiometer should be representative of the
general site area. The given application will govern the collection of solar
or net radiation data.
