  1. CM-SAF TOA radiation status report D. Caprion Royal Meteorological Institute of Belgium CM-SAF Board Meeting , Offenbach, 18-19/4/2005

  2. Overview • Changes to processing system • Status input products: GERB/SEVIRI • Status input products: CERES CM-SAF Board Meeting , Offenbach, 18-19/4/2005

  3. Changes visible to users • Running in operational mode since December 2004 - data available from December to February • Implementation of a status web site CM-SAF Board Meeting , Offenbach, 18-19/4/2005

  4. Demonstration of the status web site • Web site available at: http://gerb.oma.be/cm_saf/status.html Dynamical site based on status log files. Status log files updated after each operation. CM-SAF Board Meeting , Offenbach, 18-19/4/2005

  5. Demonstration of the status web site CM-SAF Board Meeting , Offenbach, 18-19/4/2005

  6. Demonstration of the status web site CM-SAF Board Meeting , Offenbach, 18-19/4/2005

  7. Demonstration of the status web site CM-SAF Board Meeting , Offenbach, 18-19/4/2005

  8. Internal changes • Implementation of new log files • Give more information: in particular specify the type of errors and warnings. • Integration of the High Resolution process • Data needed for surface flux products CM-SAF Board Meeting , Offenbach, 18-19/4/2005

  9. Status input products: GERB/SEVIRI • Currently used as input in order of priority: • GERB (not released) • GERB-like from SEVIRI data • Product file contains the list of input files that were actually used. • No more correction of the GERB/SEVIRI data in the CM-SAF software, will be done in near-real time GERB Processing. CM-SAF Board Meeting , Offenbach, 18-19/4/2005

  10. GERB status • Planned release: September 2005 • Planned reprocessing: as soon as possible • Known data quality problems: • Spectral response (affects TRS) • Known problem: TET for hot desert • Clear sky ocean flux estimation • Instrument in safe mode during eclipse seasons CM-SAF Board Meeting , Offenbach, 18-19/4/2005

  11. Status input products: CERES • Currently used: ES9, Terra, FM1, Edition 1 • Available up to February 2005 • Better: ES9, Terra/FM1 + Aqua/FM3, Edition 2 • Available up to Dec 2003 • More advanced: SRBAVG • Better angular models, better spatial resolution • Still waiting for ! • Currently only available for TRMM up to 2000 CM-SAF Board Meeting , Offenbach, 18-19/4/2005

  12. Conclusions • Continue to check operational chains. • GERB data release planned for September 2005. • So reprocessing..... CM-SAF Board Meeting , Offenbach, 18-19/4/2005
