摘要

In this work we present the evolution of tropospheric nitrogen dioxide (NO 2 ) content over several important European cities during 2005?￠????2014 using space observations and ground-based in-situ measurements. The NO 2 content was derived using the daily observations provided by the Ozone Monitoring Instrument (OMI), while the NO 2 volume mixing ratio measurements were obtained from the European Environment Agency (EEA) air quality monitoring stations database. The European cities selected are: Athens (37.98???° N, 23.72???° E), Berlin (52.51???° N, 13.41???° E), Bucharest (44.43???° N, 26.10???° E), Madrid (40.38???° N, 3.71???° W), Lisbon (38.71???° N, 9.13???° W), Paris (48.85???° N, 2.35???° E), Rome (41.9???° N, 12.50???° E), and Rotterdam (51.91???° N, 4.46???° E). We show that OMI NO 2 tropospheric column data can be used to assess the evolution of NO 2 over important European cities. According to the statistical analysis, using the seasonal variation, we found good correlations (R > 0.50) between OMI and ground-based in-situ observations for all of the cities presented in this work. Highest correlation coefficients (R > 0.80) between ground-based monitoring stations and OMI observations were calculated for the cities of Berlin, Madrid, and Rome. Both types of observations, in-situ and remote sensing, show an NO 2 negative trend for all of locations presented in this study.
