Abstract: The Indian MST radar at Gadanki India was used for a brief experiment starting on April 21, 2014. The method used by the ADP (Atmospheric Data Processor) to calculate the kinetic energy of turbulence at Gadanki, the ADP can only be changed on one polarisation at a time for analysis. In areas with light winds, the ADP method and the conventional method for calculating TKE are very similar. The traditional method frequently produces TKE in areas with stronger winds because the beam-broadening correction is greater than the observed spectral width. It is suggested that the uncertainty in the radar beam’s effective width is the cause of some of the issues with the conventional approach. The modified ADP method provides total kinetic energy on the beam parallel to the predominant wind in every region. The spectral widths that have been observed and this are probably well-known. In the afternoons of both April and May, the values of total kinetic energy from the ADP method are constant with height before dropping quickly to about 9 km. The diurnal range of total kinetic energy at some point in this period is found to be approximately 5 dB below 12 km and from about 15 to 19 km, near the troposphere, with maximum values through local afternoon. The data from May cover an entire diurnal period.
