| Zusammenfassung |
| We use a recently proposed spectral sampling technique for measurements of
atmospheric transmissions called the Spectral Structure Parameterization (SSP) in order to retrieve total water vapor columns (WVC) from reflectivity
spectra measured by the Global Ozone Monitoring Experiment (GOME). SSP provides a good compromise between efficiency and speed when performing
retrievals on highly structured spectra of narrow-band absorbers like water
vapor. We show that SSP can be implemented in a radiative transfer scheme which treats both direct-path absorption and absorption by singly-scattered
light directly. For the retrieval we exploit a ro-vibrational overtone band
of water vapor located in the visible around 590 nm. We compare our results
to independent values given by the data assimilation model of ECMWF. In addition, results are compared to those obtained from the more accurate, but
more computationally expensive, Optical Absorption Coefficient Spectroscopy
(OACS). |
