TEMPERATURE TURBULENCE PROBE FOR ATMOSPHERIC BOUNDARY-LAYER STUDIES

In the conventional application of temperature turbulence probes to atmospheric boundary layer studies, not much attention is paid to exact evaluation of frequency response. The need for this evaluation and a new technique for its achievement are described. A sample result obtained using one of the probes developed at Thumba, Trivandrum is also presented. Thorough knowledge of the frequency response of the probe obtained from accurately calibrating it helps one to establish the spectral behavior of temperature turbulence spectrum with increased confidence. The inertial subrange can be easily separated out which makes interpretation of the spectrum easier.
