Sioux Falls SurfRad Station
The tower, radiometer platform and solar tracker at Sioux Falls SURFRAD station, June, 2003. The EROS LandSat receiving antenna dome is visible in the background.
Rad platform
The main platform of the SurfRad station (left) includes, from left to right, a Multi-Filter Rotating Shadowband Radiometer (MFRSR), a photosynthetically active radiometer (PAR), a UV-B radiometer, and a pyranometer measuring global downwelling irradiance. The solar tracker (right) holds a Normal Incidence Pyrheliometer (left side, pointing at the sun), a pyrgeometer (left top), and a pyranometer(right top). Both instruments on top of the tracker are shaded from direct sunlight by the shading mechanism of the tracker.
