© 2004 The MITRE Corporation. All rights reserved NPOESS Motivation for HDF5 n Several product types representing different processing levels n Many specific products n Complex products n High data rates –Source ~3 x 15 Mbps –Delivery >10x higher n Interoperability with user systems n Interface consistency n User community familiarity n Maturity n Performace n Sustainability

© 2004 The MITRE Corporation. All rights reserved For NPP/NPOESS Users n 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 n Interface Control Documents and subsidiary configuration management documents between users and NPOESS will establish the details n Looking for honest balance between NPOESS requirements & user requirements –Within allowed program scope –FOM is overall program cost

© 2004 The MITRE Corporation. All rights reserved Development status n Mostly done –Defined application scope –Data model –Method for incorporating NSDI metdata into data model –Concept for query metadata in User Block n In work –Styles/conventions for all products –Consistent product design n How much reformatting of heritage products? –Test data sets –Compound or heterogeneous data product files n Open issues –User utility features & tools –Continuity of support
