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

Demonstration of the status web site

Web site available at:

http://gerb.oma.be/cm_saf/status.htmlDynamical site based on status log files.

Status log files updated after each operation.

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

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.

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

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
