The Niwot Ridge TundraLab is located at 11,600 feet on the continental divide at the University of Colorado Mountain Research Station facility. This site is subject to extreme winds, spindrift, and rime icing. University of Colorado infrastructure at the site provides meteorological data and a web camera. Internet access makes it an ideal 'back-yard' test site for polar technology. UNAVCO maintains a test platform consisting of an enclosure and solar power system that is used for testing instrumentation, communications, and power system options.
The Aerogen 4 turbine has survived ~2 years operation under high winds and icing conditions found at this site. The turbine continues to operate, with power now diverted to a dump load while testing of the Trimble NetR9 is in progress. The power logic problems affecting remote polar operation of the NetR9 have been isolated, and testing is ongoing at Niwot Ridge and UNAVCO to verify that design modifications have addressed these problems.
Removed Forgen 500 turbine and installed Aerogen 4 turbine. The Aerogen turbine has performed very well on the Polar Plateau under extreme cold and relatively light winds; this test is to evaluate the suitability of this turbine for operation in high-wind environments with "mild" cold.
