| Dear GRAS SAF GTS User

Issued 2010-06-30 14:30 UTC

Due to a software upgrade of the GRAS processor at EUMETSAT 
there will be a risk of a brief outage of GRAS SAF level 2 data tomorrow
( 2010-07-01 ). The changes will not affect the quality of the data.

Please see enclosed message from EUMETSAT.

Subject: GRAS outage last Saturday (26.06.2010) - and a reminder for a GRAS update
Date: 2010-06-28 09:58 UTC
From: Christian Marquardt

As I'm writing to you all anyway, I'd like to give a reminder that we will 
upgrade the operational GRAS processing to version 2.16.1 on Thursday. One of 
the changes in the configuration is that data after POD resets will only be 
flagged for 4 hours (currently 8), as the present setting is indeed overly 
pessimistic. 

We have also made a number of internal changes which will allow us to support 
enhanced data products from GSN in the future; an extrapolation of the 
ionospheric correction will also open up the possibility to perform raw 
sampling measurements higher up in the troposphere without affecting the 
geometrical optics processing which is in operations currently. Please note
that these changes will not be activated on Thursday, but only in the coming 
weeks as we need still need to finalize the required changes in the downstream 
processing at the GRAS SAF. We will inform you about these changes seperately.

With kind regards,

 Christian.
