[ROLSS] GERB-2 reprocessing status

[Nicolas Clerbaux]

Dear GERB data users,

This is just to inform you about reprocesing status at RMIB before the next 
week meeting. 

The reprocessing period covers 1 Feb. 2004, when MSG-1 was declared 
operational, to end of march 2006, when the "Edition 1 software" has been 
implemented in the near real time processing. The data from 2003 (satellite 
at 10.5W) will be reprocessed in a second time (TBC). 

We have started the reprocessing activities in september by a complete 
rewriting of our MSG1 SEVIRI archive on LTO3 tapes (about 50 days of SEVIRI 
data/tape). During this preliminary operation we have made the archive as 
complete as possible by retrieving the missing data to the UMARF, the 
EUMETSAT archive. The clearsky reflectance images (which are the reference 
for the cloud retrieval) have been reprocessed for the entire period 
(2004-2006).   

We have now initiated the actual GERB data reprocessing. It has been decided 
to reprocess backward in time starting from the 31 March 2006, at least in a 
first time. You can check the current status of the reprocessing on our web 
page in the 'news" section (you may need to scroll a bit)

The reprocessing factor is currently about 4, meaning that 4 days of data are 
reprocessed in 1 day. We can then expect that the 26 months will be 
reprocessed in about 5 months. We still have to validate the reprocessed 
data, to  renamed them  "Edition-1", and transferred them back to the RAL.

It is possible to reprocess some period in priority. I think that Jacqui has 
already collected your wishes and is setting up a plan for the reprocessing.

Have a good week-end,

Nicolas.
