Comparison of In-Situ, Satellite and Ground-Based Remote Sensing Retrievals of Liquid Cloud Microphysics During MACLOUD
Optional Fields
Cloud Microphysics Remote Sensing SYRSOC FAAM PROBE ICE
Two flights have been performed by the FAAM BAe 146-301 large Atmospheric Research Aircraft in the coastal atmosphere of Mace Head, Ireland, on the 9th and the 10th of December 2010 in the framework of the Marine Aerosol-CLOUD Interactions (MACLOUD) field campaign to study the microphysics of two liquid stratocumuli. Instruments onboard the FAAM BAe aircraft provided in situ measurements of the main liquid cloud microphysical variables. The latest-generation cloud microphysics retrieval method SYRSOC (SYnergistic Remote Sensing Of Cloud) has been compared with the microphysics observed by the in-situ aircraft measurements and with the METEOSAT Second Generation geostationary system, the Spinning Enhanced Visible and InfraRed Imager (SEVIRI). Synergistic profiling from LIDAR, Doppler k(a)-band cloud RADAR and humidity and temperature microwave radiometer have been used by SYRSOC to retrieve profiles of cloud droplet number concentration (CDNC), droplet effective radius (R-eff) and liquid water content (LWC) and timeseries of cloud optical thickness (COT) from the two observed stratocumuli. Temporally and spatially co-located SEVIRI images and aircraft overpasses have then been selected for comparison with SYRSOC microphysics. Full profiles of cloud microphysics from FAAM BAe and cloud-top microphysics from SEVIRI proved to be in very good agreement with SYRSOC. The vertically-resolved microphysics measured by the aircraft revealed a generally adiabatic structure for both stratocumuli, while SYRSOC provided lower-peak and more subadiabatic LWC profiles.
