Absorbing aerosol effect on the diffuse attenuation coefficient for downwelling irradiance at 490 nm indicator recovery quality on the northwestern shelf of the Black Sea

摘要

Coefficient of diffuse attenuation coefficient for downwelling irradiance at wavelength 490 nm (Kd (490)), obtainedfrom measurements of the MODIS device from the Aqua satellite and the effect of an absorbing aerosol on a standardsatellite product was studied. For this the event of absorbing aerosol transfer over the Black Sea northwestern shelf areawhich was diagnosed at the AERONET-OC Gloria station in the summer season of 2014 was considered. It was shownthat the presence of an absorbing aerosol in the atmosphere leads to an overestimation of the standard satellite product:Kd (490) in comparison with its value calculated from the ascending radiation spectrum direct measurements at theabove-mentioned AERONET- OC.
