	<abstract content_type="html">The purpose of this study is to perform a global search of the upper
troposphere (z&amp;ge;10 km) for enhancements of nitrogen dioxide and
determine their sources. We have searched two years (May 2003&amp;ndash;May 2005) of
OSIRIS (Optical Spectrograph and Infrared Imager System) operational NO&lt;sub&gt;2&lt;/sub&gt;
data (version 2.3/2.4) to find large enhancements in the observations by
comparing concentrations with those predicted by a photochemical model and
by identifying local maxima in NO&lt;sub&gt;2&lt;/sub&gt; volume mixing ratio. We find that
lightning is the main production mechanism responsible for the large
enhancements in OSIRIS NO&lt;sub&gt;2&lt;/sub&gt; observations as expected. Similar patterns
in the abundances and spatial distribution of the NO&lt;sub&gt;2&lt;/sub&gt; enhancements are
obtained by perturbing the lightning within the GEOS-Chem 3-dimensional
chemical transport model. In most cases, the presence of lightning is
confirmed with coincident imagery from LIS (Lightning Imaging Sensor) and
the spatial extent of the NO&lt;sub&gt;2&lt;/sub&gt; enhancement is mapped using nadir
observations of tropospheric NO&lt;sub&gt;2&lt;/sub&gt; at high spatial resolution from
SCIAMACHY (Scanning Imaging Absorption Spectrometer for Atmospheric
Chartography) and OMI (Ozone Monitoring Instrument). The combination of the
lightning and chemical sensors allows us to investigate globally the role of
lightning to the abundance of NO&lt;sub&gt;2&lt;/sub&gt; in the upper troposphere (UT). This
is the first application of satellite-based limb scattering to study upper
tropospheric NO&lt;sub&gt;2&lt;/sub&gt;. The spatial and temporal distribution of NO&lt;sub&gt;2&lt;/sub&gt;
enhancements from lightning (May 2003&amp;ndash;May 2005) is investigated. The
NO&lt;sub&gt;2&lt;/sub&gt; from lightning generally occurs at 12 to 13 km more frequently than
at 10 to 11 km. This is consistent with the notion that most of the NO&lt;sub&gt;2&lt;/sub&gt;
is forming and persisting near the cloud top altitude in the tropical upper
troposphere. The latitudinal distribution is mostly as expected. In general,
the thunderstorms exhibiting weaker vertical development (e.g. 11&amp;le;z&amp;le;13 km) extend latitudinally as far poleward as 45&amp;deg; but the
thunderstorms with stronger vertical development (z&amp;ge;14 km) tend to be
located within 33&amp;deg; of the equator. There is also the expected
hemispheric asymmetry in the frequency of the NO&lt;sub&gt;2&lt;/sub&gt; enhancements, as most
were observed in the Northern Hemisphere for the period analyzed.</abstract>
