Remote and Ground-Based Sensing of Air Polluted by Nitrogen Dioxide in the Dnepropetrovsk Region (Ukraine)

Data of atmospheric remote sensing in Dnepropetrovsk region have been obtained for different periods (2001, 2004, 2005, 2006 and 2010) from five points located within the Dnepropetrovsk region. Current ground-based stationary research has been carried out at three observation laboratories controlling air pollution during the last 15 years. This paper analyzes the annual mean of the NO2 concentration, on a regional (south east of Ukraine) scale. A tendency for increased nitrogen dioxide concentrations in the air around cities such as Dnepropetrovsk, Dneprodzerzhinsk and Krivoy Rog is found. The average nitrogen dioxide concentrations registered at all these cities' observation stations have exceeded the maximum permissible concentration values by as much as three to four times during the last decade.
