	<abstract content_type="html">Atmospheric remote sensing from satellite is an essential component of the
observational strategy deployed to monitor atmospheric pollution and
changing composition. The IASI nadir looking thermal infrared sounder
onboard MetOp will provide 15 years of global scale observations for a
series of key atmospheric species, with unprecedented spatial sampling and
coverage. This paper gives an overview of the instrument&apos;s capability for
measuring atmospheric composition in the perspective of chemistry and air
quality studies. The assessment is made in terms of species, accuracy and vertical
information. Global distributions are presented for CO, CH&lt;sub&gt;4&lt;/sub&gt;, O&lt;sub&gt;3&lt;/sub&gt;
(total and tropospheric), HNO&lt;sub&gt;3&lt;/sub&gt;, NH&lt;sub&gt;3&lt;/sub&gt; and volcanic SO&lt;sub&gt;2&lt;/sub&gt;. Local
distributions of organic species measured during fire events, such as
C&lt;sub&gt;2&lt;/sub&gt;H&lt;sub&gt;4&lt;/sub&gt;, CH&lt;sub&gt;3&lt;/sub&gt;OH, HCOOH, and PAN are also shown. For each species
or process, the link is made to specialized papers in this issue.</abstract>
