Abstract:Line parameter errors can contribute significantly to the total errors in retrievals of terrestrial atmospheric ozone concentration profiles using the strong 9.6-$mu$m band, particularly for nadir-viewing experimentsfootnote{J.~Worden textit {et al.}, textit{J.~Geophys.~Res.} underline{textbf{109}} (2004) 9308-9319.}. Detailed knowledge of the interfering ozone signal is also needed for retrievals of other atmospheric speciesfootnote{R.~Beer textit {et al.}, textit{Geophys.~Res.~Lett.} underline{textbf{35}} (2008) L09801.} in this spectral region. We have determined Lorentz air-broadening and pressure-induced shift coefficients along with their temperature dependences for a number of transitions in the $nu_3$ fundamental band of $^{16}$O$_3$. These results were obtained by applying the multispectrum nonlinear least-squares fitting techniquefootnote{D.~Chris Benner textit {et al.}, textit{JQSRT} underline{textbf{53}} (1995) 705-721.} to a set of 31 high-resolution infrared absorption spectra of O$_3$ recorded at temperatures between 160 and 300 K with several different room-temperature and coolable sample cells at the McMath-Pierce Fourier transform spectrometer at the National Solar Observatory on Kitt Peak. We compare our results with other available measurements and with the ozone line parameters in the HITRAN databasefootnote{L.~S.~Rothman textit {et al.}, textit{JQSRT} underline{textbf{130}} (2013) 4-50.} .
