    1. NPOESS Preparatory Project (NPP) Overview

    2. NPP Mission Overview

    3. Page-3 NPP Origins NPP is a joint partnership between NASA’s Science Mission Directorate and the NPOESS Integrated Program Office (IPO) initiated in 1998 Feasibility study began in November 1998 Formulation began in November 1999 NASA Confirmation Review completed in November 2003 The partnership provides both organizations with considerable cost savings while achieving their key program objectives: To provide NASA with continuation of a group of global change observations initiated by the Earth Observing System (EOS) TERRA, AQUA, and Aura missions To provide the NPOESS operational community with pre-operational risk reduction demonstration and validation for selected NPOESS instruments, and algorithms, as well as the ground system

    5. Page-5 Mission Segments and Responsibilities

    6. Page-6 NPP Developers

    7. Page-7 Mission Data Products NPP (and later the NPOESS Space Segment) will produce sensor data for processing by the NPOESS Interface Data Processing Segment (IDPS) The IDPS will produce Environmental Data Records (EDR’s) of geophysical products in an operational environment while minimizing data latency NASA, NOAA, and other agencies will leverage the operational EDR’s in performing climate research ADS will archive the IDPS xDRs (RDRs, SDRs, EDRs) SDS is intended to be a research tool in support of NASA’s efforts
