Abstract
The importance of studying the vertical distribution of aerosol plumes is prominent in regional and climate studies. The new Generalized Aerosol Retrieval from Radiometer and Lidar Combined data algorithm (GARRLiC) provides this opportunity combining active and passive ground-based remote sensing from lidar and sunphotometer measurements. Here, we utilize GARRLiC capabilities for the characterization of Saharan dust and marine particles at the Eastern Mediterranean region during the Characterization of Aerosol mixtures of Dust And Marine origin Experiment (CHARADMExp). Two different case studies are presented, a dust-dominated case which we managed to characterize successfully in terms of the particle microphysical properties and their vertical distribution and a case of two separate layers of marine and dust particles for which the characterization proved to be more challenging.
Highlights
Information about aerosol characterization is becoming an important topic in the context of current and future Earth Observation missions (e.gFlex, CarbonSat, EARTHCARE, ADM-Aeolus missions of the European Space Agency (ESA))
The campaign was located in the remote Finokalia station, which belongs to the Aerosols, Clouds, and Trace gases Research InfraStructure Network (ACTRIS - http://www.actris.net/), and its location provides favorable conditions for unobstructed monitoring of marine, dust and smoke particles along with their mixtures
The synergy of active with passive remote sensing has been extensively tried mainly using the sunphotometer data as ancillary information for the lidar retrieval (e.g. [2; 3]), with GARRLiC algorithm it is the first time that sunphotometer and lidar measurements are both incorporated in the retrieval of the particle microphysical properties
Summary
Information about aerosol characterization is becoming an important topic in the context of current and future Earth Observation missions (e.gFlex, CarbonSat, EARTHCARE, ADM-Aeolus missions of the European Space Agency (ESA)). The. CHARADMExp campaign (http://charadmexp.gr) was funded by ESA and was held in June and July 2014 to study the optical, microphysical and chemical properties of the Saharan dust and marine particles, as the most abundant aerosols of Eastern Mediterranean. The campaign was located in the remote Finokalia station, which belongs to the Aerosols, Clouds, and Trace gases Research InfraStructure Network (ACTRIS - http://www.actris.net/), and its location provides favorable conditions for unobstructed monitoring of marine, dust and smoke particles along with their mixtures. The synergy of active with passive remote sensing has been extensively tried mainly using the sunphotometer data as ancillary information for the lidar retrieval [2; 3]), with GARRLiC algorithm it is the first time that sunphotometer and lidar measurements are both incorporated in the retrieval of the particle microphysical properties. In [1] it is shown that GARRLiC manages to characterize successfully cases of dust mixed with urban or smoke aerosols
