The Penn State SURFRAD station. In the foreground is the main SURFRAD
platform with a ventilated pyranometer, a PAR, and broadband UVB radiometer;
the datalogger enclosure, UV power supply and station power
distribution boxes are mounted on posts underneath the main platform.
Directly north of the main platform is the UPS enclosure. Next to that is
solar tracker with a pyrheliometer for measuring direct solar radiation, and
a pyranometer and pyrgeometer, both ventilated and shaded, for measuring
diffuse solar and downwelling infrared radiation. In the background is the
10-meter tower with a pyranometer and pyrgeometer facing downward to
measure upwelling solar and infrared radiation, respectively. Also
at the top of the tower are a wind monitor, and air temperature and relative
humidity sensors. (JPEG 674x767, 55 kb)
