Zusammenfassung |
Retrievals of aerosol microphysical properties (effective radius, volume and
surface-area concentrations) and aerosol optical properties (complex index of
refraction and single-scattering albedo) were obtained from a hybrid
multiwavelength lidar data set for the first time. In July 2011, in the
Baltimore–Washington DC region, synergistic profiling of optical and
microphysical properties of aerosols with both airborne (in situ and remote
sensing) and ground-based remote sensing systems was performed during the
first deployment of DISCOVER-AQ. The hybrid multiwavelength lidar data set
combines ground-based elastic backscatter lidar measurements at 355 nm with
airborne High-Spectral-Resolution Lidar (HSRL) measurements at 532 nm and
elastic backscatter lidar measurements at 1064 nm that were obtained less
than 5 km apart from each other. This was the first study in which optical and
microphysical retrievals from lidar were obtained during the day and directly
compared to AERONET and in situ measurements for 11 cases. Good agreement was
observed between lidar and AERONET retrievals. Larger discrepancies were
observed between lidar retrievals and in situ measurements obtained by the
aircraft and aerosol hygroscopic effects are believed to be the main factor
in such discrepancies. |
