Assessment of spectroscopy for IASI
Comparison with HITRAN and GEISA, in particular for water vapour, and
real IASI spectra, compared to simulations with ECMWF provided
radiosondes, lead to the conclusion that in particular water vapour needs
to be validated, and the continuum reinvestigated.
In the discussion urgent areas to investigate were considered to be line
coupling, (which should be independent of the data bases) and non LTE.
IASI related spectroscopy problems with H2O and CO2 as first priority
