... Climate Data Record (CDR) Science Support • Includes development, production, reprocessing, stewardship, and distribution • Assumes data from all NPOESS certified sensors and mitigation sensors / sources • Covers about 30 Climate Change Science Program essential climate variables • Will be covered in more detail in following presentation June 19, 2007 16 Pre-Decisional Document: Assessment involves preliminary ROM cost estimates only PREPUBLICATION COPY -- SUBJECT TO FURTHER EDITORIAL CORRECTION 70

... Free Flyer Climate Satellite • Would fly in formation with NPOESS PM to provide imager data • Two options were examined: – Research spacecraft • Planned 5-year mission • Single string development with selective redundancy • Inexpensive, non-standard launch vehicle • Ground segment leverages existing systems. – Operational spacecraft • Planned 7-year mission with additional redundancy • Standard launch vehicle • Additional investment in ground segment • Current cost estimate range for a 3-sensor satellite is approximately $700M - $1100M – CDR Science Support is an additional $300M - $450M June 19, 2007 17 Pre-Decisional Document: Assessment involves preliminary ROM cost estimates only PREPUBLICATION COPY -- SUBJECT TO FURTHER EDITORIAL CORRECTION 71

... Altimetry Options • NPOESS sun-synchronous orbits are NOT ideal for precision altimetry • Flight of an altimeter on NPOESS is NOT recommended • For this analysis, "free flyer" satellites in the NOAA / EUMETSAT JASON series are assumed – Three satellites beyond JASON 2 required to provide coverage to 2026 – Costs estimated for JASON 3 , 4, and 5 – Advanced altimeter costs also estimated • May replace JASON class missions starting with JASON 4 • Independent of this study, U.S. Navy is working with the IPO to develop costs and options to procure an operational oceanography radar altimeter • Current total cost estimate for a series of 3 missions ranges from approximately $1.5B - $2.1B – CDR Science Support is an additional ~$200M – Current cost estimate for a single JASON follow-on is approximately $470M with the potential for 50/50 cost sharing with partners June 19, 2007 18 Pre-Decisional Document: Assessment involves preliminary ROM cost estimates only PREPUBLICATION COPY -- SUBJECT TO FURTHER EDITORIAL CORRECTION 72
