Sensitivity of TOMS aerosol index to boundary layer height: Implications for detection of mineral aerosol sources
[1] The TOMS aerosol index (AI) is proposed as a powerful tool in determining the sources of mineral aerosols. The sensitivity of the AI to the height of the aerosol layer has been noted previously, but the implications of this sensitivity for deducing sources has not been explicitly considered. Here, we present a methodology and sensitivity test to show the importance of spatial and temporal v...
متن کاملExtraction of Aerosol Properties and Surface Reflectance from Polder Data over Land
It is as yet very difficult to extract optical properties of atmospheric aerosols from satellite data over land. The PARASOL/ POLDER observes the reflectance and polarization of a target quasi-simultaneously in multi-viewing angles at wavelengths of 490nm, 670nm and 865nm. In this study, a new estimation method of aerosol properties using the polarized radiance effectively is described. The pol...
متن کاملAerosol absorption over the clear-sky oceans deduced from POLDER-1 and AERONET observations
[1] We estimate aerosol absorption over the clear-sky oceans using aerosol geophysical products from POLDER-1 space measurements and absorption properties from ground-based AERONET measurements. Our best estimate is 2.5 Wm 2 averaged over the 8-month lifetime of POLDER-1. Low and high absorption estimates are 2.2 and 3.1 Wm 2 based on the variability in aerosol singlescattering albedo observed ...
متن کاملMarine organic aerosol and biological oceanic activity
Marine aerosol constitutes one of the most important natural aerosol systems at the global level and comprises both organic and inorganic components of primary and secondary origin. This work presents new results on organic marine aerosol properties and its link with oceanic biological productivity. Laboratory experiments have shown that sea-spray aerosol originating from highly biologically ac...
متن کاملSatellite Retrieval of Aerosol Properties over Bright Reflecting Desert Regions
Since about 30 % of the land surface are covered with arid and desert conditions of soil, bright grounds and their aerosol emissions are of essential importance for the investigation of general aerosol impact in climate. Therefore retrievals of aerosol properties from spaceborne platforms need to include retrieval approaches, working over this conditions. An approach to retrieve aerosol propert...
