<abstract>
<p>We report the ozone absolute absorption cross section between 350–470 nm,
the minimum between the Huggins and Chappuis bands, where the ozone cross
section is less than 10&lt;sup&gt;&amp;minus;22&lt;/sup&gt; cm&lt;sup&gt;2&lt;/sup&gt;. Ozone spectra were acquired using
an incoherent broadband cavity enhanced absorption spectrometer, with three
channels centered at 365, 405, and 455 nm. The accuracy of the measured
cross section is 4–30%, with the greatest uncertainty near the minimum
absorption at 375–390 nm. Previous measurements vary by more than an
order of magnitude in this spectral region. The measurements reported here
provide much greater spectral coverage than the most recent measurements.
The effect of O&lt;sub&gt;3&lt;/sub&gt; concentration and water vapor partial pressure were
investigated, however there were no observable changes in the absorption
spectrum most likely due to the low optical density of the complex.</p>
