Reference radiative transfer calculations

Spectroscopic databases

  • 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

Follow model-name links to access full summaries of model features and development status provided by the model developers and updated after each ITSC by the RTSP working group.

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 ECMWF Tech. Memo. 525, May 2007 for details.
