NDE Product Development Why NOAA’s NDE Project enhances NPOESS Products NPOESS will provide data to four central processing facilities, called “Centrals,” via its Interface Data Processing Segment (IDPS) and to remote field terminals via direct satellite-to-ground communications links. The Centrals will be responsible for providing NPOESS global coverage System Mission Data (SMD) to environmental satellite users. Field terminals will provide real-time access to regional coverage data feeds directly from NPOESS satellites. NESDIS will operate the NOAA Central. The Air Force Weather Agency (AFWA), Fleet Numerical Meteorology and Oceanography Center (FNMOC), and Naval Oceanographic Office (NAVOCEANO) will operate the other three Centrals. The distribution of the NPOESS products to the civilian community will be the responsibility of the NPOESS Data Exploitation (NDE) system at the NOAA Central.  NDE Product Types A fundamental design assumption of NPOESS is that each Central will modify and redistribute the products to satisfy the needs of its customers. NDE will manage two categories of product enhancement: “tailoring” and “NOAA-unique product” development. NOAA-unique product development is necessary to support missions that are specific to NOAA, as opposed to data used by all Centrals. NOAA-unique products are augmented environmental products constructed from NPOESS Data Records. They will be generated by procedures (e.g., algorithms) that use NPOESS Data Records (xDRs) as a basis of products containing data values that are different from those in the xDRs as received from NPOESS. NOAA-unique products may be generated by combining products from different data sources to provide other environmental information. In tailoring activities, versions of NPOESS Data Records are provided in alternative formats and views. For example, all of the NPOESS products will be delivered to NESDIS in Hierarchical Data Format 5 (HDF5), a standard used by only a few of NESDIS’ customers. NDE will reformat the data for these customers before dissemination. Other forms of tailoring include alternative map projections, coverage areas, aggregations, grids, and compression approaches. Whenever possible, NDE will provide the software to enable the end users to do the tailoring on their own systems. NESDIS currently provides its customers with approximately 270 environmental data products derived from polar satellite observations. Many of these products are different views of the same data. When fully operational, NPOESS satellites will deliver over 150 products. NESDIS’s mission requires an extension of similar tailoring capabilities into the NPOESS era.
