Global Two-Channel AVHRR Retrievals of Aerosol Properties over the Ocean for the Period of NOAA-9 Observations and Preliminary Retrievals Using NOAA-7 and NOAA-11 Data

Source: Journal of the Atmospheric Sciences:;2002:;Volume( 059 ):;issue: 003:;page 262

Author(s): Geogdzhayev, Igor V.; Mishchenko, Michael I.; Rossow, William B.; Cairns, Brian; Lacis, Andrew A.

Publisher: American Meteorological Society

Abstract: Described is an improved algorithm that uses channel 1 and 2 radiances of the Advanced Very High Resolution Radiometer (AVHRR) to retrieve the aerosol optical thickness and Ångström exponent over the ocean. Specifically ...

New Statistical Model for Variability of Aerosol Optical Thickness: Theory and Application to MODIS Data over Ocean

Source: Journal of the Atmospheric Sciences:;2015:;Volume( 073 ):;issue: 002:;page 821

Author(s): Alexandrov, Mikhail D.; Geogdzhayev, Igor V.; Tsigaridis, Kostas; Marshak, Alexander; Levy, Robert; Cairns, Brian

Publisher: American Meteorological Society

Abstract: novel model for the variability in aerosol optical thickness (AOT) is presented. This model is based on the consideration of AOT fields as realizations of a stochastic process that is the exponent of an underlying Gaussian ...

Intercomparison of Satellite Retrieved Aerosol Optical Depth over the Ocean

Source: Journal of the Atmospheric Sciences:;2004:;Volume( 061 ):;issue: 005:;page 499

Author(s): Myhre, Gunnar; Stordal, Frode; Johnsrud, Mona; Ignatov, Alexander; Mishchenko, Michael I.; Geogdzhayev, Igor V.; Tanré, Didier; Deuzé, Jean-Luc; Goloub, Philippe; Nakajima, Teruyuki; Higurashi, Akiko; Torres, Omar; Holben, Brent

Publisher: American Meteorological Society

Abstract: For an 8-month period aerosol optical depth (AOD) is compared, derived over global oceans with five different retrieval algorithms applied to four satellite instruments flown on board three satellite platforms. The Advanced ...

Earth Observations from DSCOVR EPIC Instrument

Author(s): Marshak, Alexander; Herman, Jay; Adam, Szabo; Karin, Blank; Carn, Simon; Cede, Alexander; Geogdzhayev, Igor; Huang, Dong; Huang, Liang-Kang; Knyazikhin, Yuri; Kowalewski, Matthew; Krotkov, Nickolay; Lyapustin, Alexei; McPeters, Richard; Meyer, Kerry G.; Torres, Omar; Yang, Yuekui

Publisher: American Meteorological Society

Abstract: AbstractThe National Oceanic and Atmospheric Administration (NOAA) Deep Space Climate Observatory (DSCOVR) spacecraft was launched on 11 February 2015 and in June 2015 achieved its orbit at the first Lagrange point (L1), ...

A Comparison of Model- and Satellite-Derived Aerosol Optical Depth and Reflectivity

Source: Journal of the Atmospheric Sciences:;2002:;Volume( 059 ):;issue: 003:;page 441

Author(s): Penner, Joyce E.; Zhang, Sophia Y.; Chin, Mian; Chuang, Catherine C.; Feichter, Johann; Feng, Yan; Geogdzhayev, Igor V.; Ginoux, Paul; Herzog, Michael; Higurashi, Akiko; Koch, Dorothy; Land, Christine; Lohmann, Ulrike; Mishchenko, Michael; Nakajima, Teruyuki; Pitari, Giovanni; Soden, Brian; Tegen, Ina; Stowe, Lawrence

Publisher: American Meteorological Society

Abstract: The determination of an accurate quantitative understanding of the role of tropospheric aerosols in the earth's radiation budget is extremely important because forcing by anthropogenic aerosols presently represents one of ...
