Reviewing the development of a ground-based FTIR water vapour profile analysis
IMK-ASF, Forschungszentrum und Universität Karlsruhe, Karlsruhe, Germany
Abstract. Analytic algorithms effectively applied for ground-based infrared remote sensing of many different atmospheric trace gases can be rather ineffective for the remote sensing of tropospheric water vapour profiles. Reasons are the large vertical gradient and variability of water vapour as well as its large concentrations. We review the most important features of analysis and radiative transfer modeling required for monitoring tropospheric water vapour profiles by ground-based FTIR 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 inversion. Furthermore, the introduction of an interspecies constraint allows for a monitoring of HDO/H2O ratio profiles.
