Book Description
This report offers technical comparison of the two United States operational space programs that are based on the capabilities of polar-orbiting environmental satellites. The U.S. Air Force manages and conducts the operations of the Defense Meteorological Satellite Program (DMSP); the National Oceanic and Atmospheric Administration has the same responsibilities with respect to the NOAA Polar-orbiting Operational Environmental Satellite (POES) program. The report examines the major missions and goals of the two programs, the management and operational procedures that they follow, and the support they extend to each other and to other Federal agencies. Detailed discussions are provided about the specifications and performance characteristics of the spacecraft, sensors, onboard systems, command and control systems, and communications systems employed by the two programs. An extensive relative analysis of the operation and uses of the DMSP and POES imaging and atmospheric sounding instruments is provided. Other sensors and systems are discussed, as is the joint agreement between DOD and NOAA for sharing their satellite data and data processing load. Nonmeteorological users of DMSP and POES data are described. The organization and content of the satellite data archive are presented. Near-future system improvements and longer-term mission requirements are also discussed. (Author).

Book Description
This unique collection of government documents provides comprehensive coverage of all aspects of current and planned American weather satellites, with material from NOAA, NASA, and independent reviews of the troubled replacement program. Contents: Launch Delayed - NOAA Faces Key Decisions on Timing of Future Satellites * Improvements Needed in NOAA's Mitigation Strategies as It Prepares for Potential Satellite Coverage Gaps * Polar Weather Satellites - NOAA Needs To Prepare for Near-term Data Gaps * Geostationary Weather Satellites - Launch Date Nears, but Remaining Schedule Risks Need to be Addressed * History of the NOAA Satellite Program * NOAA Satellite Conference 2015 Summary Report * NOAA-N Satellite, POES Program * NOAA Response - A Review of NOAA's Satellite Program: A Way Forward * NOAA's GOES R - Next Generation Satellite * NOAA Knows...Earth-Observing Satellites * Options for Modernizing Military Weather Satellites * Bridging the Gap: America's Weather Satellites and Weather Forecasting The National Oceanic and Atmospheric Administration's (NOAA) $10.9 billion Geostationary Operational Environmental Satellite-R (GOES-R) program recently delayed the planned launch of the first satellite in the new series from March 2016 to October 2016. Based on its ongoing work, GAO found that the decision to delay the launch was due to poor schedule performance over the last few years (losing more than 10 days a month on average), recent technical issues with key components, and little schedule margin as the program entered integration testing. The October 2016 launch date may also be delayed if additional technical challenges arise or if schedule performance remains poor. NOAA recently changed assumptions about the expected lifespan of existing GOES satellites from 7 to 10 years based on the longevity of prior satellites. However, the analysis supporting this change is over 10 years old. Even with this extension, NOAA may fall short of its policy of having 2 operational satellites and 1 backup satellite in orbit. The agency faces an 11 month gap in backup coverage until GOES-R is operational, during which time there would be only 2 operational satellites. Any further delays in the GOES-R launch date could exacerbate that gap. NOAA is now facing important decisions on when to launch the remaining satellites in the GOES-R series to maximize satellite coverage while minimizing development and storage costs. Based on its ongoing work, GAO found that NOAA's $11.3 billion Joint Polar Satellite System (JPSS) program is making progress toward the planned launch of the JPSS-1 satellite in March 2017. However, the program has experienced technical issues that have affected internal schedule deadlines, such as an issue with debris in an instrument's subsystem that delayed its delivery by approximately 8 months, and faces key risks in the remainder of development. NOAA is also facing the risk of a potential near-term gap in polar data prior to the launch of the JPSS-1 satellite. Similar to the decision on the GOES satellites, in April 2015, NOAA revised its assumptions about the expected life of the satellite that is currently in-orbit by adding up to 4 years, which would reduce the chance of a near-term gap. However, risks to the performance and health of the on-orbit satellite, and to development of the JPSS-2 satellite could increase the risk of a gap. Also, NOAA faces key decisions on timing the development and launch of the remaining JPSS satellites to ensure satellite continuity while balancing the possibility that satellites could last much longer than anticipated.

Book Description
During the Conference on Air-Sea Interaction in January 1986, it was suggested to me by David Larner of Reidel Press that it may be timely for an updated compendium of air-sea interaction theory to be organized, developed, and published. Many new results were emerging at the time, i.e., results from the MARSEN, MASEX, MILDEX, and TOWARD field projects (among others) were in the process of being reported and/or published. Further, a series of new experiments such as FASINEX and HEXOS were soon to be conducted in which new strides in our knowledge of air-sea fluxes would be made. During the year following the discussions with David Larner, it became apparent that many of the advances in air-sea interaction theory during the 1970s and 1980s were associated with sponsor investments in satellite oceanography and, in particular, remote sensing research. Since ocean surface remote sensing, e.g., scatterometry and SAR, requires intimate knowledge of ocean surface dynamics, advances in remote sensing capabilities required coordinated research in air-sea fluxes, wave state, scattering theory, sensor design, and data exploitation using environmental models. Based on this interplay of disciplines, it was decided that this book be devoted to air sea interaction and remote sensing as multi-disciplinary activities.

Book Description
The National Polar-Orbiting Environmental Satellite System (NPOESS) is a tri-agency acquisition -- managed by the DoD & NASA -- which experienced escalating costs, schedule delays, & technical difficulties. These factors led to a June 2006 decision to restructure the program, thereby decreasing the program¿s complexity, increasing its estimated cost to $12.5 billion, & delaying the first two satellites by 3 to 5 years. The author was asked to: (1) assess progress in restructuring the acquisition; (2) evaluate progress in establishing an effective mgmt. structure; (3) assess the reliability of the cost & schedule estimate; & (4) identify the status & key risks facing the program¿s major segments. Includes recommendations. Charts & tables.
