This book was released on 2004-10-13 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report reviews NASA's solid-earth science strategy, placing particular emphasis on observational strategies for measuring surface deformation, high-resolution topography, surface properties, and the variability of the earth's magnetic and gravity fields. The report found that NASA is uniquely positioned to implement these observational strategies and that a number of agency programs would benefit from the resulting data. In particular, the report strongly endorses the near-term launch of a satellite dedicated to L-band InSAR measurements of the land surface, which is a key component of the U.S. Geological Survey's hazards mitigation program and the multi-agency EarthScope program.

This book was released on 2010-03-25 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA's space and Earth science program is composed of two principal components: spaceflight projects and mission-enabling activities. Most of the budget of NASA's Science Mission Directorate (SMD) is applied to spaceflight missions, but NASA identifies nearly one quarter of the SMD budget as "mission enabling." The principal mission-enabling activities, which traditionally encompass much of NASA's research and analysis (R&A) programs, include support for basic research, theory, modeling, and data analysis; suborbital payloads and flights and complementary ground-based programs; advanced technology development; and advanced mission and instrumentation concept studies. While the R&A program is essential to the development and support of NASA's diverse set of space and Earth science missions, defining and articulating an appropriate scale for mission-enabling activities have posed a challenge throughout NASA's history. This volume identifies the appropriate roles for mission-enabling activities and metrics for assessing their effectiveness. Furthermore, the book evaluates how, from a strategic perspective, decisions should be made about balance between mission-related and mission-enabling elements of the overall program as well as balance between various elements within the mission-enabling component. Collectively, these efforts will help SMD to make a good program even better.

This book was released on 2009-12-03 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: We will show in this monograph some possibilities of using the potential of satellite passive microwave radiometric methods for the analysis of variations of heat and dynamic processes in the ocean–atmosphere interface in a wide range of time scales – from mesometeorogical (hours, daily) to seasonal (month) and multiyear (climatic) ones. The most essential mechanisms of intercommunication of natural microwave radiation of the system ocean–atmosphere (SOA) with the vertical turbulence fluxes of sensible, latent heat, as well as the momentum at the boundary of the SOA are studied. We will consider the turbulence heat fluxes as the factors generated by the c- otic movements in the atmosphere, when every small individual part of air is moved irregularly. Here, one can observe a transfer of the energy from large-scale to sma- scales; the average distance between the air particles is increased with a time. Also, the potential of remote sensing the characteristics of heat and water adv- tion and their accumulation in the atmosphere boundary layer are demonstrated. In these studies, we mean mainly the middle and high latitudes of the North Atlantic, which are forming the weather conditions and climatic trends over Europe and European territories of the Russia.

Available in PDF, EPUB and Kindle. Book excerpt: The book describes different approaches to the analysis of heat and dynamic processes in the ocean-atmospheric interface with satellite passive radiometric observations at microwaves. It examines the feasibility of determining synoptic, seasonal and year-to-year variations of sensible, latent and momentum fluxes to a useful accuracy using the DMSP SSM/I and EOS Aqua AMSR-E data directly from the measured brightness temperatures. An important object in the studies is the North Atlantic with emphasize on the areas with high midlatitude cyclon activity: here the main results have been obtained by combining data from the vessel experiments NEWFOUEX-88, ATLANTEX-90 and the data of microwave radiometers from the DMSP and EOS Aqua satellites. The role of vertical turbulent and horizontal advective heat transfer in forming interrelations between the brightness temperature of the system ocean-atmosphere and surface heat fluxes in the range of synoptic time scales is analyzed. Special sections of the book describe some results of analysis of reaction of the system ocean-atmosphere on passing of the tropical cyclone Katrina (August 2005) in the Florida Strait as well as a behavior of the system in the period of a time preceding to origination the cyclone Humberto (September 2007) in the Mexico Gulf. The long-term goal of this research is the search for effects and regularities, which can explain the reasons for the tropical cyclones appearance. Some characteristics of the tropical cyclones (brightness temperature and heat contrasts, etc.) are compared with those for midlatitude cyclones. At the same time as covering a key topic area with implications for global warming research, this text is also usefull to students who want to gain insight into application of satellite microwave radiometric methods for studying the air-sea interaction. Key themes: microwave radiometry, air-sea interaction, midlatitude and tropical cyclones, atmosphere boundary layer, heat and momentum surface fluxes.

Available in PDF, EPUB and Kindle. Book excerpt: Today, there exists an integrated, large-scale satellite system to track sea-level rise, its speed, causes, and impacts. Building it was a struggle every step of the way. It was the most vivid and potentially consequential program within NASA’s larger Earth Science directorate. How did it happen? Who did what? Why? This book seeks to answer such questions. It goes back to the origins of NASA’s interest in the oceans in the 1960s and first true ocean satellite, Seasat, in 1978. After three months of operation, Seasat failed. But before it did, it showed how much satellites could tell about the ocean’s dynamics. In many ways, sea-level rise is the clearest and most understandable result of a warming planet.

Download or read book Extending the Effective Lifetimes of Earth Observing Research Missions written by National Research Council and published by National Academies Press. This book was released on 2005-11-18 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: While NASA Earth Science missions are planned on the basis of a specified lifetime, often they are able to function beyond the end of that period. Until recently NASA had no formal mechanism for determining whether those missions should be extended or whether the resources necessary for the extension should be applied to new missions. In August 2004, when NASA merged Earth and space sciences, the agency began using the Science Review process to make those extension determinations. NASA had asked the NRC to assess extension review processes, and after the merger, this study focused on the Science Review process. This report presents an assessment of that process and provides recommendations for adapting it to Earth Science missions.

This book was released on 2012-09-03 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the effects of natural and human-induced changes on the global environment and their implications requires a foundation of integrated observations of land, sea, air and space, on which to build credible information products, forecast models, and other tools for making informed decisions. The 2007 National Research Council report on decadal survey called for a renewal of the national commitment to a program of Earth observations in which attention to securing practical benefits for humankind plays an equal role with the quest to acquire new knowledge about the Earth system. NASA responded favorably and aggressively to this survey, embracing its overall recommendations for Earth observations, missions, technology investments, and priorities for the underlying science. As a result, the science and applications communities have made significant progress over the past 5 years. However, the Committee on Assessment of NASA's Earth Science Program found that the survey vision is being realized at a far slower pace than was recommended, principally because the required budget was not achieved. Exacerbating the budget shortfalls, NASA Earth science programs experienced launch failures and delays and the cost of implementing missions increased substantially as a result of changes in mission scope, increases in launch vehicle costs and/or the lack of availability of a medium-class launch vehicle, under-estimation of costs by the decadal survey, and unfunded programmatic changes that were required by Congress and the Office of Management and Budget. In addition, the National Oceanic and Atmospheric Administration (NOAA) has made significant reductions in scope to its future Earth environmental observing satellites as it contends with budget shortfalls. Earth Science and Applications from Space: A Midterm Assessment of NASA's Implementation of the Decadal Survey recommends a number of steps to better manage existing programs and to implement future programs that will be recommended by the next decadal survey. The report also highlights the urgent need for the Executive Branch to develop and implement an overarching multiagency national strategy for Earth observations from space, a key recommendation of the 2007 decadal survey that remains unfulfilled.

Download or read book Steps to Facilitate Principal-Investigator-Led Earth Science Missions written by National Research Council and published by National Academies Press. This book was released on 2004-04-21 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principal-investigator (PI) Earth science missions are small, focused science projects involving relatively small spacecraft. The selected PI is responsible for the scientific and programmatic success of the entire project. A particular objective of PI-led missions has been to help develop university-based research capacity. Such missions, however, pose significant challenges that are beyond the capabilities of most universities to manage. To help NASA's Office of Earth Science determine how best to address these, the NRC carried out an assessment of key issues relevant to the success of university-based PI-led Earth observation missions. This report presents the result of that study. In particular, the report provides an analysis of opportunities to enhance such missions and recommendations about whether and, if so, how they should be used to build university-based research capabilities.
