	<abstract content_type="html">Long-term satellite measurements of nitrogen dioxide in the troposphere are
used in combination with a continental scale air quality model in order to
verify and improve available estimates of multi-annual changes of emissions
of nitrogen oxides (NO&lt;sub&gt;x&lt;/sub&gt;) in Europe and the Mediterranean area between
1996 and 2005. As a result, a measurement-based data set of NO&lt;sub&gt;x&lt;/sub&gt; emissions on a 1&amp;deg; by 1&amp;deg; grid and averaged over summer months is
elaborated.
&lt;br&gt;&lt;br&gt;
The results are compared with emission data based on the EMEP emission
inventory. Our data are in agreement with the EMEP estimates suggesting a
general decline in the level of NO&lt;sub&gt;x&lt;/sub&gt; emissions in Western and Central
European countries (France, Germany, Great Britain and Poland). Over
Southern Europe and for shipping emissions, neutral to positive trends are
found both for the inverted and bottom-up emissions. In contrast,
considerable differences between both data sets are found in some other
countries. In particular, significant negative trends instead of the
positive ones in the &quot;bottom-up&quot; inventory are found for the Balkan
countries, Russia and Turkey. The NO&lt;sub&gt;x&lt;/sub&gt; emission trends derived from
satellite measurements demonstrate larger spatial heterogeneity than those
calculated with the EMEP data, especially in Russia and Ukraine.
&lt;br&gt;&lt;br&gt;
The obtained estimates of the decadal trends in NO&lt;sub&gt;x&lt;/sub&gt; emissions for Great
Britain are found to be consistent with independent data from the U.K.
Automatic Urban and Rural Network (AURN). It is also found that using our
emission estimates yields better agreement of model calculations with
near-surface ozone measurements of the European EMEP network.</abstract>
