DEPLOYMENT AND INSTALLATION
Mount the sensor to a solid surface with the nylon mounting screw provided, included thermally-insulated base
needs to be mounted between the sensor and the surface it is being mounted to. To accurately measure
atmospheric longwave radiation incident on a horizontal surface, the sensor should be approximately level
(longwave radiation from atmosphere is diffuse, so perfect level of the sensor is not required). An Apogee
Instruments model AL-100 leveling plate is recommended for this purpose. To facilitate mounting on a cross arm,
an Apogee Instruments model AM-110 mounting bracket is recommended.

Sensors must be carefully mounted in order to view the desired target surface (sky or ground) and avoid including
unwanted surfaces/objects in the field of view, thereby averaging unwanted radiation with the target radiation.
The sensor should be mounted such that obstructions (e.g., weather station tripod/tower or other
instrumentation) do not obstruct the sensor field of view. Once mounted, the green cap should be removed from
the sensor. The green cap can be used as a protective covering for the sensor when it is not in use.
