摘要

Our goal is to study the vertical aerosol transport in the planetary boundary layer (PBL) with lidar. For this reason we made first attempts to use the eddy correlation technique on the basis of highly resolved aerosol and vertical-wind data to calculate turbulent aerosol fluxes. The Doppler wind lidar of the Max Planck Institute for Meteorology Hamburg (MPI) and the aerosol Raman lidar of the Institute for Tropospheric Research Leipzig (IfT) were operated next to each other at the IfT site in September 2003. With both instruments, we performed measurements in the convective boundary layer under a variety of meteorological conditions. From the measurements we obtained combined data sets of aerosol backscatter and vertical wind with a resolution of 45 m and 10 s in the lower PBL and 60 m and 30 s in the upper PBL. Analysis of the power spectra of the individual time series and of the cospectra of the combined data sets shows that the relevant frequency range of eddies is covered. First results of aerosol flux profiles are presented.
