The NPOESS Integrated Program Office and its principal contractors -- Raytheon and Northrop-Grumman -- are prepraring for the launch of the NPP risk-reduction mission in 2006. This presentation will review program status, and how HDF will be used to deliver NPOESS products at the domestic weather centrals and worldwide field terminals.

13. NPOESS Motivation for HDF5
Several product types representing different processing
levels
Many specific products
Complex products
High data rates
– Source ~3 x 15 Mbps
– Delivery >10x higher
Interoperability with user systems
Interface consistency
User community familiarity
Maturity
Performace
Sustainability

14. For NPP/NPOESS Users
IDPS distributes data at “wholesale”, our users redistribute
at “retail”; provide value-added and product integration
– Users are operational weather Centrals; field terminals
operators; archives (CLASS); and research community
Interface Control Documents and subsidiary configuration
management documents between users and NPOESS will
establish the details
Looking for honest balance between NPOESS requirements
& user requirements
– Within allowed program scope
– FOM is overall program cost

15. Development status
Mostly done
– Defined application scope
– Data model
– Method for incorporating NSDI metdata into data model
– Concept for query metadata in User Block
In work
– Styles/conventions for all products
– Consistent product design
How much reformatting of heritage products?
– Test data sets
– Compound or heterogeneous data product files
Open issues
– User utility features & tools
– Continuity of support
