Outline

NPOESS / NPP Overview Role for HDF5 Status

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.

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


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


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
