| Zusammenfassung |
| Retrieval products for temperature, water vapour and ozone have been
obtained from spectral radiances measured by the Infrared
Atmospheric Sounding Interferometer flying onboard the first
European Meteorological Operational satellite. These products have
been used to check the consistency of the forward model and its
accuracy and the expected retrieval performance. The study has been
carried out using a research-oriented forward-inverse methodology,
called φ-IASI, that the authors have specifically developed
for the new sounding interferometer. The performance of the
forward-inversion strategy has been assessed by comparing the
retrieved profiles to profiles of temperature, water vapour and
ozone obtained by co-locating in space and time profiles from
radiosonde observations and from the European Centre for
Medium-Range Weather Forecasts analysis. Spectral residuals have
also been computed and analyzed to assess the quality of the forward
model. Two versions of the high-resolution transmission molecular
absorption database have been used, which mostly differ for ozone
absorption line parameters, line and continuum absorption of both
CO2 and H2O molecules. Their performance has been assessed by
inter-comparing the results, and a consistent improvement in the
spectral residual has been found when using the most updated
release. |
