green closed folder category icon ICESat 1 (2)
ICESat is a small satellite mission to fly the Geoscience Laser Altimeter System (GLAS) in a near-polar orbit in 2001. GLAS will accurately measure the elevation of the Earth's ice sheets, clouds, and land.
green closed folder category icon Landsat 7 (10)
This includes sites that provide information on the ETM Plus (ETM+), sensor with new panchromatic and thermal bands plus history of the Landsat program and data uses.
green closed folder category icon SAGE III (1)
The SAGE III mission on the Russian Meteor 3M-1 spacecraft seeks to enhance our understanding of natural and human-derived atmospheric processes by providing high latitude long-term measurements of the vertical structure of aerosols, ozone, water vapor, and other important trace gases in the upper troposphere and stratosphere.
green closed folder category icon TRMM (6)
The Tropical Rainfall Measuring Mission (TRMM) is a joint mission between NASA and the National Space Development Agency (NASDA) of Japan. It was designed to monitor and study tropical rainfall and the associated release of energy that helps to power the global atmospheric circulation shaping both weather and climate around the globe.
green closed folder category icon Terra (4)
The Terra satellite is the flagship of EOS. It will provide global data on the state of the atmosphere, land, and oceans, as well as their interactions with solar radiation and with one another. Visit this site to explore and learn about the scientific objectives of this flagship mission. This includes sites that provide information on MODIS, MISR, MOPITT, CERES and ASTER instruments.

    blue right-pointing arrow ACRIMSAT (Solar Studies) Homepage - A series of Active Cavity Radiometer Irradiance Monitors (ACRIMs) provides long-term, precise measurements of the total amount of the Sun's energy that falls on our planet's surface, oceans, and atmosphere.  [keywords: ACRIMSAT, ACRIM, Solar Studies] (Added: 23-May-1999 Hits: 1040)  [Spider Link]
    blue right-pointing arrow Aqua Homepage - Aqua (formerly EOS-PM). The Focus for the Aqua Project is the multi-disciplinary study of the Earth's Interrelated Processes (atmosphere, oceans, and land surface) and their relationship to earth system changes. Aqua, Latin for water, is a NASA Earth Science satellite mission named for the large amount of information that the mission will be collecting about the Earth's water cycle, including evaporation from the oceans, water vapor in the atmosphere, clouds, precipitation, soil moisture, sea ice, land ice, and snow cover on the land and ice. Additional variables also being measured by Aqua include radiative energy fluxes, aerosols, vegetation cover on the land, phytoplankton and dissolved organic matter in the oceans, and air, land, and water temperatures.  [keywords: Aqua, EOS PM] (Added: 23-May-1999 Hits: 928)  [Spider Link]
    blue right-pointing arrow Aura (EOS-CHEM) - Aura (formerly EOS-CHEM) The objective of the EOS Aura Mission is to study the chemistry and dynamics of the Earth's atmosphere from the ground through the mesosphere. Aura (Latin for breeze) was launched July 15, 2004. The design life is five years with an operational goal of six years. Aura flies in formation about 15 minutes behind Aqua. Aura is part of the Earth Observing System (EOS), a program dedicated to monitoring the complex interactions that affect the globe using NASA satellites and data systems.  [keywords: EOS, CHEM-1, Chemistry] (Added: 23-May-1999 Hits: 940)  [Spider Link]
    blue right-pointing arrow Earth Observatory - The purpose of NASA's Earth Observatory is to provide a freely-accessible publication on the Internet where the public can obtain new satellite imagery and scientific information about our home planet. The web site focuses on Earth's climate and environmental change.  [keywords: Earth Observatory] (Added: 22-May-1999 Hits: 3289)  [Spider Link] pop
    blue right-pointing arrow Earth System Science Pathfinder Project Homepage - The Earth System Science Pathfinder (ESSP) Project is a component of the Earth Science Enterprise (ESE) that addresses unique, specific, highly-focused mission requirements in Earth science research. The ESSP program is an innovative approach for addressing Global Change Research by providing periodic "Windows of Opportunity" to accommodate new scientific priorities and infuse new scientific participation into the Earth Science Enterprise.  [keywords: Earth System Science Pathfinder, ESSP] (Added: 23-May-1999 Hits: 1016)  [Spider Link]
    blue right-pointing arrow JASON-1 Homepage - Jason is an oceanography mission to monitor global ocean circulation, discover the tie between the oceans and atmosphere, improve global climate predictions, and monitor events such as El Niņo conditions and ocean eddies. The Jason-1 satellite carries a radar altimeter and it is a follow-on mission to the highly successful TOPEX/Poseidon mission. It is joint mission between France and USA. The satellite will be launched in May 2000.  [keywords: JASON-1] (Added: 23-May-1999 Hits: 947)  [Spider Link]
    blue right-pointing arrow NMP/EO-1 Homepage - Earth Observing-1 (EO-1) is the first satellite in NASA's New Millennium Program Earth Observing series. The EO missions will develop and validate instruments and technologies for space-based Earth observations with unique spatial, spectral and temporal characteristics not previously available.  [keywords: NMP,EO-1, Earth Observer-1] (Added: 23-May-1999 Hits: 1022)  [Spider Link]
    blue right-pointing arrow NMP/EO-2 (SPARCLE - 2001) Homepage - The New Millennium Program's (NMP) second mission, Earth Observing 2 (EO-2), will demonstrate the ability of a lidar (laser radar) method of measuring winds from space using the SPAce Readiness Coherent Lidar Experiment (SPARCLE) onboard the Space Shuttle.  [keywords: NMP, EO-2, Earth Observer 2, SPARCLE] (Added: 23-May-1999 Hits: 925)  [Spider Link]
    blue right-pointing arrow QuikSCAT Homepage - The SeaWinds on QuikSCAT mission is a "quick recovery" mission to fill the gap created by the loss of data from the NASA Scatterometer (NSCAT), when the satellite it was flying on lost power in June 1997. QuikSCAT is scheduled to launch from California's Vandenberg Air Force Base aboard a Titan II vehicle in early summer 1999, and will continue to collect important ocean wind data that was begun by NSCAT in September 1996. The SeaWinds instrument on the QuikSCAT satellite is a specialized microwave radar that measures near-surface wind speed and direction under all weather and cloud conditions over Earth's oceans.  [keywords: QuickSCAT, SeaWinds, NSCAT] (Added: 23-May-1999 Hits: 967)  [Spider Link]
    blue right-pointing arrow SeaWinds (ADEOS-II) - The SeaWinds scatterometer is a specialized microwave radar that measures near-surface wind velocity (both speed and direction) under all weather and cloud conditions over Earth's oceans. The experiment is a follow-on mission and continues the data series initiated in 1996 by the NSCAT. SeaWinds uses a rotating dish antenna with two beams. The antenna radiates microwave pulses at a frequency of 13.4 gigahertz across broad regions on Earth's surface. SeaWinds will collect data in a continuous 1,800-kilometer-wide band, making approximately 400,000 measurements per day.  [keywords: SeaWinds, ADEOS-II] (Added: 23-May-1999 Hits: 1036)  [Spider Link]
