| Zusammenfassung |
| The atmospheric boundary layer height was derived at two locations in the
city of Lanzhou (China) and its suburb rural area Yuzhong. The aerosol
backscatter lidar measurements were analysed using a wavelet technology and
the parcel method was applied to profiling microwave radiometer
observations. For a few occasions the average boundary layer height and
entrainment zone thickness was derived in convective situations at Yuzhong.
Results from selected observation days show that both datasets agree in
strong convective situations. However, for weak convective situations the
lidar measurements reveal boundary layer heights that are higher compared to
the microwave observations, because a decrease of the thermal boundary layer
height does not directly lead to a change of aerosols in that altitude
layer. Finally, the entrainment zone thicknesses are compared with
theoretical predictions, and the results show that the measurements are
compatible with theoretical models. |
