Obstruction for the global
horizontal illuminance sensor

Comments

The illuminance sensors are calibrated by the manufacturers.
The irradiance sensors are pre-calibrated by the manufacturers and re-calibrated by Meteorologishes Observatorium Hamburg:
- in the laboratory by comparison to a standard pyranometer
- outdoors at clear-sky-conditions by comparison to the direct solar radiation measured by a pyrheliometer.
All other sensors are calibrated by the manufacturers.

View 1 of the station

Comments

View towards South. The beam carrying the instruments is directed exactly north-south. The global horizontal and diffuse horizontal sensors are seen on the right. The sensors measuring illuminances are seen on the left. Further to the left, the south vertical irradiance sensor is seen. The tree is exactly in the south. As seen from the beam, this is an obstruction less than 1°.

Comments

View towards North. The beam for the instruments is seen on the left. It carries the global horizontal and diffuse horizontal sensors at its northward end. The sensors measuring illuminances are seen on the right. There is no horizontal obstruction in this direction.
