What Can Be Measured by the Temperature Profiler?

V. P. Yushkov

The ability of the ground-based microwave temperature profiler to retrieve the lapse rates in the lower part of the atmospheric boundary layer is verified by analyzing the long-term observation se¬ries. It is demonstrated that if the stratification of the whole boundary layer is either unstable or suffi¬ciently homogeneous, measured and retrieved with a mast lapse rates are quite similar. If the stratifica¬tion is stable, the retrieval algorithms require correction. Demonstrated is the potential for the more ac¬curate retrieving of the temperature gradient over the surface layer by means of the angular scanning. This enables using the data of temperature profilers for estimating the boundary layer stability and the Monin–Obukhov scale.
