Meteorological sensors
The weather station includes air temperature and relative humidity sensors mounted in naturally aspirated sun shield (left) with wind speed and wind direction instruments (right) mounted on the roof of the entrance building.
Wind Set
Tom points to wind set installed near roof level at site entrance
Radiometers
Gary Wood and Mary Jane Hale discuss the new weather station installation. A pyranometer (foreground) measures total hemispheric solar irradiance. A pyrheliometer on an automatic solar tracker (white) measures direct normal irradiance.
Radiometers and Tracker
Weather station components include (L/R) a pyrheliometer for measuring direct normal solar irradiance mounted in an automatic solar tracker, a pyranometer mounted on a support post for total hemispheric solar irradiance, and a tipping bucket rain gauge.
Solar Tracker
Rik inspects final installation of automatic solar tracker with pyrheliometer (left) and pyranometer mounted on support post (right). Note - the microwave communication antenna was lowered below the pyranometer field of view.
