We define requirements for information tools and network informing community on state PM pollutions that will be created. This provide long-term observations could included AirBase network. The comprehensive review in-situ satellite measurements is provided as well description current state-of-the-art Air Quality...
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....
We use a global chemical transport model, GEOS–Chem (Goddard Earth Observing System – Chemistry model), to simulate the spatial and temporal distribution of atmospheric concentrations specific aerosol types over Belarus-Ukraine region for period 2010–2013.
