  • 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.
