GES DAAC Transition Issues
Last Update: August 2, 2006
Over the time period February through September, 2006 the GES DAAC MODIS
functionality will transfer to MODAPS. This includes all production,
archive, and distribution functions.
All MODAPS production for forward processing (Collection 4 and 5) and
reprocessing (Collection 5) will be performed using L0 data acquired
directly from EDOS. The Level 1 and Atmospheres Archive and Distribution
System (LAADS) will be the principal mechanism for the archive and
distribution of data products to the end user. However, some data products
will be maintained on "rolling" data pools for limited durations and some
subscriptions will be distributed from MODAPS. All data products archived
by LAADS/Data Pools will be maintained on disk. The archives, excluding the
MODAPS production disks, will total in excess of 500 TB. Further details
can be obtained from the following areas of this web site:
Production,
Distribution, and
Documents.
The transition schedule is complex and detailed and has been derived by
MODAPS and GES DAAC staff and reviewed and approved by ESDIS staff. This
schedule is available in MSProject form
(MSProject Transition Schedule). Details of
the Transitions Planned and
Transitions Completed are given in
following pages.
