Abstract. An optimization approach has been developed for simultaneous retrieval of aerosol properties and normalized water-leaving radiance (nLw) from multispectral, multiangular, polarimetric observations over ocean. The main features the method are (1) use a simplified bio-optical model to estimate nLw, followed by an empirical refinement within specified range improve its accuracy; (2) improved algorithm convergence stability applying constraints on spatial smoothness loading Chlorophyll...
Abstract. The paper presents some results of the study on aerosol variability in period from 2003 to 2011 over Eastern Europe region, with latitude ranging 40° N 60° and longitude 20° E 50° E. analysis was based POLDER/PARASOL POLDER-2/ADEOS satellites AERONET (AErosol RObotic NETwork) ground-based sun photometer observations. optical thickness (AOT) studied area is characterized by values (referenced 870 nm wavelength) 0.05 0.2, except for July–August 2010 strong forest peat wildfires when...
Abstract. The paper presents an investigation of aerosol seasonal variations in several urban–industrial regions Ukraine. Our analysis optical and physical parameters is based on the sun-photometer 2008–2013 data from two urban ground-based AERONET (AErosol RObotic NETwork) sites Ukraine (Kyiv, Lugansk) as well satellite POLDER instrument for areas We also analyzed one site Belarus (Minsk) order to compare with Ukrainian sites. Aerosol amount depth (AOD) values atmosphere columns over large...
AbstractA concentration-weighted trajectory method for aerosol source localization based on joint statistical analysis of column volume concentrations and back-trajectory data was used to estimate the spatial distribution sources in East-European region. The concentration measured at five AERONET network sites, Belsk, Minsk, Kyiv, Moldova/Kishinev, Sevastopol, were used. geographical areas responsible increased content monitoring sites mapped separately coarse-mode fine-mode fractions....
The distribution and properties of atmospheric aerosols on a global scale are not well known in terms determination their effects climate. This mostly is due to extreme variability aerosol concentrations, properties, sources, types. Aerosol climate impact comparable the effect greenhouse gases, but its influence more difficult measure, especially with respect microphysical evaluation anthropogenic effect. There many satellite missions studying terrestrial atmosphere, such as MISR/Terra,...

Abstract. The paper presents an investigation of aerosol seasonal variations in several urban sites the East European region. Our analysis optical and physical parameters is based on sun-photometer 2008–2012 data from three ground-based AERONET Ukraine (Kyiv, Kyiv-AO, Lugansk) one site Belarus (Minsk), as well satellite POLDER instrument for areas Ukraine. Aerosol amount thickness values exhibit peaks spring (April–May) late summer (August), whereas minimum are seen autumn over Kyiv Minsk...

Concentration weighted trajectory method for aerosol sources retrieval technique based on the joint statistical analysis of column volume concentrations and back-trajectory data was used to estimate spatial distribution particles arrived in Central Ukraine region observed at Kyiv site data. The concentration AERONET network were used. It shown that north-east territories (in relation monitoring site) give small contribution coarse mode content. events increased have been caused by south-east...
