Reference radiative transfer calculations
- access the latest edition of the HITRAN database and associated updates and documentation
- access the latest versions of the complete GEISA and
GEISA/IASI databases, and associated software and documentation.
New considerations for modellers
- Ozone absorption in the AMSU 183 GHz channels should be included in RT models
(brightness temperature variations are of the order of 0.5 K).
- The 23 GHz water vapour absorption line half-widths have been revised based on
results from the ARM site. A study of the resulting
impact for AMSU and SSMI radiances
has been provided by Bill Bell and Stephen English (UKMO).
Line-by-line radiative transfer models

model features and development status provided by the model developers and

Marco Matricardi (ECMWF) has prepared a report of intercomparisons between LBL codes used
in the development of fast RT models for use in NWP. See
