Assessing of surface-ozone concentration in Bucharest, Romania, using OML and satellite data

The aim of the paper is to assess the spatial distribution of surface-ozone concentrations for Bucharest urban agglomeration by running OML (“Operationelle Meteorologiske Luftkvalitetsmodeller” - Operational Meteorological Air Quality Model) dispersion model. Two data sets from 2009 were used to initialize the model for: (i) air quality data base of the National Network of Air Quality Monitoring (NNAQM); (ii) satellite data obtained from OMI (Ozone Monitoring Instrument) on board of AURA satellite. The potential of satellite data used in air quality assessment in lower troposphere, at local scale was also tested by comparison to data from air-quality monitoring stations. The intercomparison of simulated and measured data emphasized that satellite data can be used for assessment of air quality.
