Workshop Objectives
Workshop Organisation
ENVISAT Validation Workshop - Frascati - 9–13 December 2002
The objectives of the Envisat Validation Workshop are:
to review the Level 2 product algorithms using the results of the validation campaigns,
to review the geophysical consistency of the Level 2 processor products,
to provide an error estimation of the Level 2 products,
where needed, to recommend instrument re-calibration and algorithm development.
Workshop objectives
The Envisat Validation Workshop will review the first results of the validation of the Envisat geophysical data.
ENVISAT Validation Workshop - Frascati - 9–13 December 2002
The validation activities will continue after the workshop,throughout the entire mission lifetime.
More specifically, the main validation phase (i.e. with intensive validation activities) will be completed in 2003, whereas the long term validation phase will be associated to e.g. algorithm improvement or instrument degradation.
Specific validation workshops will be held (on a per instrument basis) all throughout 2003. Ideally a draft schedule will drawn up during the workshop.
A ERS/ENVISAT Symposium is now planned for March/April 2004.
Validation activities after the Workshop
ENVISAT Validation Workshop - Frascati - 9–13 December 2002
During the next 6 months, ESA will concentrate on :
- providing the data corresponding to the validation campaigns (e.g. 2002 balloon campaign),
- processing the complete real-time data, in order to stop the accumulation of un-processed data (e.g. to provide the data corresponding to winter 2003 balloon campaign).
Reprocessing of the complete set of data acquired in 2002 (backlog) will be initiated as soon as the PDS is upgraded to allow concurrent real time processing and backlog processing (from July 2003), using updated algorithms.
For L1/L2 products, new algorithm versions will be implemented as agreed with Validation Teams and Quality Working Groups, and as operationally possible.
L1 reprocessing is foreseen once during the mission.
L2 reprocessing of complete archived data will be possible not more than every 1.5 to 2 years, dependant on the data volume.

Every presenter/author should deliver BOTH a copy of the presentation material (PowerPoint) AND a (typically) 10 page article.
Instructions to authors can be found in the workshop web pages.
The Proceedings will be published by ESA Publications Division about 2 months after the workshop, as Special Publication SP-531.
