Using the spectral width from the Airda16000 low stratospheric wind profiler radar, removing the non-turbulent contaminations, then obtaining the spectral width contributed by turbulence, the turbulent dissipation rate could be estimated. The height profiler, diurnal and seasonal variability of turbulent dissipation rate in the troposphere were studied. Results show that: First, the turbulent dissipation rate distributed between 10-6~10-2 m2·s-3 on clear air days, and decreased with the increase of height. Second, it had remarkable diurnal variability below 3 km, which increased in the midday and decreased in the evening and morning, also, there was a delay of diurnal variability with time, the dissipation rate did not display the tendency of di
