This brochure provides details about NASA?s GRACE mission. Gravity controls everything from the motion of the ocean tides to the expansion of the entire Universe. To learn more about the mysteries of gravity, the twin Gravity Recovery and Climate Experiment (GRACE) satellites, are taking detailed measurements of Earth's gravity field. This experiment could lead to discoveries about gravity and Earth's ... Full description.

This site provides a number of Landsat 7 scene subsets as LAN files that are intended for use with Purdue University's MultiSpec software. Users also have the option of downloading the Landsat images as TIFF files in four different band combinations. Links are included to download Multi-Spec, a MultiSpec tutorial, and an introduction to remote-sensing PowerPoint presentation with detailed notes. Full description.

This brochure describes the Moderate Resolution Imaging Spectrometer (MODIS) instrument on NASA's Terra satellite. The first NASA Earth Observing System (EOS) satellite, Terra, was launched on December 18, 1999, carrying five remote sensors. The most comprehensive EOS sensor is MODIS which offers a unique combination of features: it detects a wide spectral range of electromagnetic energy; it takes ... Full description.

This brochure describes NASA's ICESat mission ((Ice, Cloud, and land Elevation Satellite), which was launched January 12, 2003. ICESat is the benchmark Earth Observing System mission for measuring ice sheet mass balance, cloud and aerosol heights, as well as land topography and vegetation characteristics. Full description.

This lithograph shows images from NASA?s Landsat 7 Enhanced Thematic Mapper Plus instrument of the Boulder, Virgin, and Gregg basins that comprise the southern portion of Lake Meade. About 96% of the water in Lake Mead is from melted snow that falls in Colorado, Utah, New Mexico, and Wyoming. During the period from May 2000 to April 2003 severe drought occurred in the western states, and Colorado ... Full description.

This 5-minute animation portrays fluctuations in the cryosphere through observations collected from a variety of satellite-based sensors. The cryosphere consists of those parts of the Earth's surface where water is found in solid form, including areas of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. In these regions, surface temperatures remain below freezing for a portion of each ... Full description.

The stories included in this annual publication primarily focus on research and recent success stories of how NASA's Earth Observing System data are being used to benefit society. Each article features data that are processed, managed, archived and distributed through NASA's Distributed Active Archive Centers and cooperating data centers. It is written for the scientifically interested public. Full description.

The educational resources and activities on this Web site teach fundamental concepts about salinity variations and the role these changes play in controlling global ocean circulation and Earth?s climate. The modules augment existing El Nino/La Nina materials with salinity-based content, provide on-line interactive tools demonstrating environmental change through data sets and in situ time-series analysis, ...
