An Analysis of Data from the Triton Sonic Wind Profiler

Second WindThe met mast is dead. Long live sodar! While it is early to make this statement emphatically, data from field tests indicates that a new generation of sodar technology is poised to replace meteorological masts for many assessment applications. This article reports on data from customers using Second Wind's Triton® sonic wind profiler in eight diverse locations. The findings show reliable reporting of valid wind data at heights that encompass the full blade sweep of commercial wind turbines. Gross data recovery was above 95%, correlation to anemometry at 60 metres was 0.97, and signal-to-noise ratios were greater than 9 at heights up to 160 metres.
