<abstract>
<p>Ground-based Fourier-transform infrared (FTIR) solar absorption spectroscopy
is a powerful remote sensing technique providing information on the vertical
distribution of various atmospheric constituents. This work presents the
first evaluation of a mid-resolution ground-based FTIR to measure
tropospheric ozone, independently of stratospheric ozone. This is
demonstrated using a new atmospheric observatory (named OASIS for
&quot;Observations of the Atmosphere by Solar absorption Infrared
Spectroscopy&quot;), installed in Créteil (France). The capacity of the
technique to separate stratospheric and tropospheric ozone is demonstrated.
Daily mean tropospheric ozone columns derived from the Infrared Atmospheric
Sounding Interferometer (IASI) and from OASIS measurements are compared for
summer 2009 and a good agreement of &amp;minus;5.6 (&amp;plusmn;16.1) % is observed.
Also, a qualitative comparison between in-situ surface ozone measurements and OASIS
data reveals OASIS&apos;s capacity to monitor seasonal tropospheric ozone
variations, as well as ozone pollution episodes in summer 2009 around Paris.
Two extreme pollution events are identified (on the 1 July and
6 August 2009) for which ozone partial columns from OASIS and
predictions from a regional air-quality model (CHIMERE) are compared
following strict criteria of temporal and spatial coincidence. An average
bias of 0.2%, a mean square error deviation of 7.6%, and a
correlation coefficient of 0.91 is found between CHIMERE and OASIS,
demonstrating the potential of a mid-resolution FTIR instrument in
ground-based solar absorption geometry for tropospheric ozone monitoring.</p>
