The ten-meter tower at Desert Rock. Instruments are: Vaisala air temperature and relative humidity probe (top left), RM Young wind monitor (top right), Eppley pyrgeometer for measuring upwelling longwave (lower left), and a Spectrosun pyranometer for measuring upwelling visible (lower right). There is also a lightning rod at top center. (102 kb)
The main platform. Instruments shown are (left to right): MFRSR, Yankee Environmental Systems UVB-1 Ultraviolet Pyranometer, LI-COR Quantum sensor for photosynthetically active radiation, ventilated Eppley pyrgeometer, ventilated Spectrosun pyranometer, and three other LI-COR detectors (on boom arm at right) for special experiments at the station.
