Aerosol and cloud properties from synergy of lidar, radar and radiometer measuremnets
The EMORAL lidar (UW), the BASTA cloud radar (LATMOS), and the HATPRO-G2 microwave radiometer (INOE) observations were conducted jointly over the PolWET peatland site in Rzecin (PULS) during the POLIMOS field campaigns (ESA).The EMORAL lidar measures in 8 channels: elastic (355/532/1064 nm), inelastic Raman (387 and 607 nm for N2, and 408 nm for H2O) and elastic cross-polarized (355 and 532 nm), with 3.75 m vertical resolution and adjustable temporal resolution (2s to 10 min). A 95-GHz Doppler cloud radar called the Bistatic Radar System for Atmospheric Studies (BASTA) uses a frequency–modulated continuous wave (FMCW) technique. The main products are reflectivity and Doppler velocity, obtained with 12.5 m, 25 m and 100 m vertical resolution and 3 s time resolution. The HATPRO-G2 microwave radiometer consists of two working bands at 22–31 and 51–58 GHz, each with seven channels. Measurements with a temporal resolution of 15 s and a height-dependent vertical resolution provide integrated water vapor, liquid water path and vertical profiles of relative humidity and temperature.During my talk the POLIMOS campaigns and the instruments will be introduced. Then I will focus on the algorithms for aerosol and cloud classification and the synergetic data products. All will be demonstrated on a case study basis.
