| Zusammenfassung |
| Collisional line-mixing is a process which is known to affect the treatment of atmospheric
spectra for several species. Recent works on the modelling of line-mixing effects will be
presented for CO2, CH4 and O3. It will be shown that the widely used Voigt profile leads to
large discrepancies with respect to measured spectra and accounting for line-mixing effects is
unavoidable to correctly model measurements. Comparisons between laboratory, atmospheric
spectra and simulations using our models show good agreements. However, small but
systematic errors on the residuals still remain indicating that more refined works on spectral
shape are needed. |
