(author)In this study trends in the tropospheric NO2 concentrations during 2005-2010 across Europe were derived from the synergistic use of OMI NO2 tropospheric columns and the chemistry transport model LOTOS-EUROS and were compared to reported NOx emissions.

Schaap, M. (author), Kranenburg, R. (author), Curier, L. (author), Jozwicka, M. (author), Dammers, E. (author), Timmermans, R. (author)The advent of satellite data has provided a source of independent information to monitor trends in tropospheric nitrogen dioxide levels. To interpret these trends, one needs to know the sensitivity of the satellite retrieved NO2 column to anthropogenic emissions. We have applied a chemistry transport model to investigate the sensitivity of the...article 2013

Velders, G.J.M. (author), Geilenkirchen, G.P. (author), de Lange, R. (author)In past years, the European limit value for average annual NO2 concentration has been exceeded in city streets and along motorways in the Netherlands. By 2015 the limit value must be adhered to in the Netherlands.
