Climate data records from environmental satellites : interim report / par Satellites,, Committee on Climate Data Records from NOAA Operational. Publication : [S.l.] : National Academies Press, 2004 . 150 p. ; , The report outlines key elements to consider in designing a program to create climate-quality data from satellites. It examines historical attempts to create climate data records, provides advice on steps for generating, re-analyzing, and storing satellite climate data, and discusses the importance of partnering between agencies, academia, and industry. NOAA will use this report - the first in a two-part study - to draft an implementation plan for climate data records. 25 cm.

Groundwater fluxes across interfaces / par Science,, Committee on Hydrologic. Publication : [S.l.] : National Academies Press, 2004 . 100 p. ; , Estimates of groundwater recharge and discharge rates are needed at many different scales for many different purposes. These include such tasks as evaluating landslide risks, managing groundwater resources, locating nuclear waste repositories, and estimating global budgets of water and greenhouse gasses. "Groundwater Fluxes Across Interfaces" focuses on scientific challenges in: the spatial and temporal variability of recharge and discharge; how information at one scale can be used at another; and the effects of groundwater on climate and vice versa. 28 cm.

Living on an active earth : perspectives on earthquake science / par Earthquakes,, Committee on the Science of. Publication : [S.l.] : National Academies Press, 2003 . 432 p. ; , The destructive force of earthquakes has stimulated human inquiry since ancient times, yet the scientific study of earthquakes is a surprisingly recent endeavor. Instrumental recordings of earthquakes were not made until the second half of the 19th century, and the primary mechanism for generating seismic waves was not identified until the beginning of the 20th century. From this recent start, a range of laboratory, field, and theoretical investigations have developed into a vigorous new discipline: the science of earthquakes. As a basic science, it provides a comprehensive understanding of earthquake behavior and related phenomena in the Earth and other terrestrial planets. As an applied science, it provides a knowledge base of great practical value for a global society whose infrastructure is built on the Earth's active crust. This book describes the growth and origins of earthquake science and identifies research and data collection efforts that will strengthen the scientific and social contributions of this exciting new discipline. 24 cm.

Opportunities in high magnetic field science / par Science,, Committee on Opportunities in High Magnetic Field. Publication : [S.l.] : National Academies Press, 2005 . 188 p. ; , High-field magnets - those that operate at the limits of the mechanical and/or electromagnetic properties of their structural materials - are used as research tools in a variety of scientific disciplines. The study of high magnetic fields themselves is also important in many areas such as astrophysics. Because of their importance in scientific research and the possibility of new breakthroughs, the National Science Foundation asked the National Research Council to assess the current state of and future prospects for high-field science and technology in the United States. This report presents the results of that assessment. It focuses on scientific and technological challenges and opportunities, and not on specific program activities. The report provides findings and recommendations about important research directions, the relative strength of U.S. efforts compared to other countries, and ways in which the program can operate more effectively. 25 cm.
