	<abstract content_type="html">This work presents observations of a series of short-lived species in
biomass burning plumes from the Infrared Atmospheric Sounding Interferometer
(IASI), launched onboard the MetOp-A platform in October 2006. The strong
fires that have occurred in the Mediterranean Basin – and particularly
Greece – in August 2007, and those in Southern Siberia and Eastern
Mongolia in the early spring of 2008 are selected to support the analyses.
We show that the IASI infrared spectra in these fire plumes contain
distinctive signatures of ammonia (NH&lt;sub&gt;3&lt;/sub&gt;), ethene (C&lt;sub&gt;2&lt;/sub&gt;H&lt;sub&gt;4&lt;/sub&gt;),
methanol (CH&lt;sub&gt;3&lt;/sub&gt;OH) and formic acid (HCOOH) in the atmospheric window
between 800 and 1200 cm&lt;sup&gt;&amp;minus;1&lt;/sup&gt;, with some noticeable differences between the
plumes. Peroxyacetyl nitrate (CH&lt;sub&gt;3&lt;/sub&gt;COO&lt;sub&gt;2&lt;/sub&gt;NO&lt;sub&gt;2&lt;/sub&gt;, abbreviated as PAN) was
also observed in some plumes and a tentative assignment of a broadband
absorption spectral feature to acetic acid (CH&lt;sub&gt;3&lt;/sub&gt;COOH) is made. For
several of these species these are the first reported measurements made from
space in nadir geometry. The IASI measurements are analyzed for plume height
and concentration distributions of NH&lt;sub&gt;3&lt;/sub&gt;, C&lt;sub&gt;2&lt;/sub&gt;H&lt;sub&gt;4&lt;/sub&gt; and CH&lt;sub&gt;3&lt;/sub&gt;OH.
The Greek fires are studied in greater detail for the days associated with
the largest emissions. In addition to providing information on the spatial
extent of the plume, the IASI retrievals allow an estimate of the total mass
emissions for NH&lt;sub&gt;3&lt;/sub&gt;, C&lt;sub&gt;2&lt;/sub&gt;H&lt;sub&gt;4&lt;/sub&gt; and CH&lt;sub&gt;3&lt;/sub&gt;OH. Enhancement ratios
are calculated for the latter relative to carbon monoxide (CO), giving
insight in the chemical processes occurring during the transport, the first
day after the emission.</abstract>
