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. (92 kb)

The instruments on the 10-meter tower include, clockwise from far left,
a pyrgeometer measuring upwelling IR, an air temperature and relative
humidity sensor, a wind speed and direction monitor, and a pyranometer
measuring upwelling visible irradiance. (27 kb)
