| Zusammenfassung |
| Due to a large vertical gradient and strong variability of water
vapour, algorithms that are effectively applied for ground-based
remote sensing of many different atmospheric trace gases can be
insufficient for the retrieval of tropospheric water vapour
profiles. We review the most important features of the retrieval and
of the radiative transfer modelling required for accurate monitoring
of tropospheric water vapour profiles by ground-based FTIR (Fourier
Transform Infrared) experiments. These are: a fit of a variety of
different water vapour lines with different strength, a logarithmic
scale inversion, a speed dependent Voigt line shape model, and a
joint temperature profile retrieval. Furthermore, the introduction
of an interspecies constraint allows for a monitoring of HDO/H2O
ratio profiles. |
