thermal infrared IASI/MetOp sounder"/> <meta name="citation_abstract" content="<p><strong class="journal-contentHeaderColor">Abstract.</strong> Atmospheric remote sounding from satellites 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's capability for measuring atmospheric composition in the perspective of chemistry and air quality. The assessment is made in terms of species, accuracy and vertical information. Global distributions are presented for CO, CH<sub>4</sub>, O<sub>3</sub> (total and tropospheric), HNO<sub>3</sub>, NH<sub>3</sub>, and volcanic SO<sub>2</sub>. Local distributions of organic species measured during fire events, such as C<sub>2</sub>H<sub>4</sub>, CH<sub>3</sub>OH, HCOOH, and PAN are also shown. For each species or process, the link is made to specialized papers in this issue.</p>"/> <meta name="citation_publication_date" content="2009/08/20"/> <meta name="citation_online_date" content="2009/08/20"/> <meta name="citation_journal_title" content="Atmospheric Chemistry and Physics"/> <meta name="citation_volume" content="9"/> <meta name="citation_issue" content="16"/> <meta name="citation_issn" content="1680-7316"/> <meta name="citation_doi" content="https://doi.org/10.5194/acp-9-6041-2009"/> <meta name="citation_firstpage" content="6041"/> <meta name="citation_lastpage" content="6054"/> <meta name="citation_author" content="Clerbaux, C."/> <meta name="citation_author_institution" content="UPMC Univ.

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's capability for measuring atmospheric composition in the perspective of chemistry and air quality. The assessment is made in terms of species, accuracy and vertical information. Global distributions are presented for CO, CH<sub>4</sub>, O<sub>3</sub> (total and tropospheric), HNO<sub>3</sub>, NH<sub>3</sub>, and volcanic SO<sub>2</sub>. Local distributions of organic species measured during fire events, such as C<sub>2</sub>H<sub>4</sub>, CH<sub>3</sub>OH, HCOOH, and PAN are also shown. For each species or process, the link is made to specialized papers in this issue.</p> </div> <div id="oldMobileDownloadBox" class="widget dark-border hide-on-desktop download-and-links"> <div class="legend journal-contentLinkColor">Download & links</div> <div class="content"> <ul class="additional_info no-bullets no-styling"> <li> <a class="triangle" data-toggle=".box-notice" data-duration="300" title="PDF Version (5097 KB)" href="https://acp.copernicus.org/articles/9/6041/2009/acp-9-6041-2009.pdf" > Article (PDF, 5097 KB) </a> </li> </ul> </div> </div> <div id="downloadBoxOneColumn" class="widget dark-border hide-on-desktop download-and-links"> <div class="legend journal-contentLinkColor">Download & links</div> <div class="content"> <ul class="additional_info no-bullets no-styling"> <li><a class="triangle" title="PDF Version (5097 KB)" href="https://acp.copernicus.org/articles/9/6041/2009/acp-9-6041-2009.pdf">Article</a> <nobr>(5097 KB)</nobr> </li> <li> <a class="triangle" title="XML Version" href="https://acp.copernicus.org/articles/9/6041/2009/acp-9-6041-2009.xml">Metadata XML</a> </li> <li><a class="triangle" href="https://acp.copernicus.org/articles/9/6041/2009/acp-9-6041-2009.bib">BibTeX</a></li> <li><a class="triangle" href="https://acp.copernicus.org/articles/9/6041/2009/acp-9-6041-2009.ris">EndNote</a></li> </ul> </div> </div> <div id="share" class="oneColumnShareMobileBox widget dark-border hide-on-desktop"> <div class="legend journal-contentLinkColor">Share</div> <div class="content row m-0 py-1"> <div class="col-auto pl-0"> <a class="share-one-line" href="https://www.mendeley.com/import/?url=https%3A%2F%2Facp.copernicus.org%2Farticles%2F9%2F6041%2F2009%2F" title="Mendeley" target="_blank"> <img src="https://www.atmospheric-chemistry-and-physics.net/mendeley.png" alt="Mendeley"/> </a> </div> <div class="col-auto"> <a class="share-one-line" href="https://www.reddit.com/submit?url=https%3A%2F%2Facp.copernicus.org%2Farticles%2F9%2F6041%2F2009%2F" title="Reddit" target="_blank"> <img src="https://www.atmospheric-chemistry-and-physics.net/reddit.png" alt="Reddit"> </a> </div> <div class="col-auto"> <a class="share-one-line last" href="https://twitter.com/intent/tweet?text=Monitoring+of+atmospheric+composition+using+the+thermal+infrared+IASI%2FMetOp+sounder https%3A%2F%2Facp.copernicus.org%2Farticles%2F9%2F6041%2F2009%2F" title="Twitter" target="_blank"> <img src="https://www.atmospheric-chemistry-and-physics.net/twitter.png" alt="Twitter"/> </a> </div> <div class="col-auto"> <a class="share-one-line" href="https://www.facebook.com/share.php?u=https%3A%2F%2Facp.copernicus.org%2Farticles%2F9%2F6041%2F2009%2F&t=Monitoring+of+atmospheric+composition+using+the+thermal+infrared+IASI%2FMetOp+sounder" title="Facebook" target="_blank"> <img src="https://www.atmospheric-chemistry-and-physics.net/facebook.png" alt="Facebook"/> </a> </div> <div class="col-auto pr-0"> <a class="share-one-line last" href="https://www.linkedin.com/shareArticle?mini=true&url=https%3A%2F%2Facp.copernicus.org%2Farticles%2F9%2F6041%2F2009%2F&title=Monitoring+of+atmospheric+composition+using+the+thermal+infrared+IASI%2FMetOp+sounder" title="LinkedIn" target="_blank"> <img src="https://www.atmospheric-chemistry-and-physics.net/linkedin.png" alt="LinkedIn"> </a> </div> <div class="col pr-0 mobile-native-share"> <a href="#" data-title="Atmospheric Chemistry and Physics" data-text="*Monitoring of atmospheric composition using the thermal infrared IASI/MetOp sounder* C.
