| Zusammenfassung |
| The HyMeX program (Hydrological cycle in Mediterranean eXperiment) aims at
improving our understanding of hydrological cycle in the Mediterranen and at a better
quantification and forecast of high-impact weather events in numerical weather prediction
models.
The first Special Observation Period (SOP1) took place in September/October 2012.
During this period two aerosol Raman lidars have been deployed at Menorca Island (Spain) :
one Water-vapor and Aerosol Raman LIdar (WALI) operated by LSCE/CEA (Laboratoire des
Sciences du Climat et de l’Environnement/Commissariat à l’Energie Atomique) and one
aerosol Raman and dual-polarization lidar (R-Man510) developed and commercialized by
LEOSPHERE company. Both lidars have been continuously running during the
campaign and have provided information on aerosol and cloud optical properties under
various atmospheric conditions (maritime background aerosols, dust events, cirrus
clouds-¦).
We will present here the results of intercomparisons between R-Man510, and WALI
aerosol lidar systems and collocated sunphotometer measurements. Limitations and
uncertainties on the retrieval of extinction coefficients, depolarization ratio, aerosol optical
depths and detection of atmospheric structures (planetary boundary layer height,
aerosol/cloud layers) will be discussed according atmospheric conditions. The results will
also be compared with theoretical uncertainty assessed with direct/inverse model of lidar
profiles. |
