Obstruction for the global
horizontal illuminance sensor

Comments

Vertical sensors are screened from reflected light coming from the ground. An horizontal matt black surface surrounds the sensors and a ring forms an artificial horizon. The top border of the ring is at the same level as the center of the sensors.
The obstructions shown above for the global horizontal illuminance sensor are all distant from the station. Therefore this representation seems to be acceptable for all sensors.

This view is looking toward West. A triple table with the global irradiance, the zenith luminance and the horizontal and vertical global illuminance sensors is on the left. The diffuse horizontal irradiance and illuminance sensors are in the center. The diffuse vertical illuminance sensors are on the right.
