Paper Abstract
As part of the Thirty Meter Telescope (TMT) site testing program, several instruments have been deployed
to characterize the turbulence profiles of the candidate sites. To make such measurements in the boundary
layer (height < 1,000m) we have installed several SODARs. Initially conceived to make 3-dimensional wind
speed profiles, this instrument is also capable of measuring the temperature fluctuation constant C2T. Such a
measurement requires calibration to become quantitative. We present in this paper a new calibration method
that relies on additional kinetic heat flux measurements. This method is the first method to be fully portable to
any other SODARs and does not rely on another turbulence profiler for cross calibration. This method will be
used to calibrate all TMT SODAR data.
