  • NASA satellite improves pollution monitoring

    NASA scientists improved watershed pollution monitoring models by incorporating satellite and ground-based observations of precipitation. The NASA data replaces weather station observations, and will allow states to monitor non-point pollution and improve water quality. The research team, led by Joseph Nigro of Science Systems and Applications, Inc., incorporated two NASA products into a computer ...

  • Satellites help locate water in Niger

    Like most sub-Saharan African countries, Niger faces problems meeting its water needs. As part of ESA’s TIGER initiative, satellite data are being used to identify surface and underground water resources in the drought-prone country.Due to the rainfall variability in time and in space, during recent years the rain-fed agriculture struggles to meet the requirements of food security in the Sahel ...

  • Dozens of new satellites planned to monitor climate

    An international strategy for deployment of dozens of new satellites to help scientists better understand global warming got a boost on Wednesday as the world's space and meteorological agencies gave their support to the World Meteorological Organization proposal at a high-level space conference.  Approval came at the end of the two day meeting last week in New Orleans, Louisiana attended by top ...

  • Study tracks ´memory´ of soil moisture

    Original story at MIT News The top 2 inches of topsoil on all of Earth’s landmasses contains an infinitesimal fraction of the planet’s water — less than one-thousandth of a percent. Yet because of its position at the interface between the land and the atmosphere, that tiny amount plays a crucial role in ...

  • Satellite data instrumental in combating desertification

    With land degradation in dryland regions continuing to worsen, the UN Convention to Combat Desertification has agreed on scientist-recommended indicators for monitoring and assessing desertification that signatory countries must report on. The landmark agreement was reached after two weeks of negotiations involving hundreds of scientists and government ministers attending the Ninth Session of the ...

  • Satellite data to improve flood forecasting

    As the residents of Queensland, Australia, turn to the mammoth task of cleaning up after the devastating floods over the last weeks, data from ESA's Earth observation satellites are showing potential for delivering more timely warnings. Through a project funded by ESA's Data User Element, observations from the Advanced Synthetic Aperture Radar (ASAR) on Envisat are now used to increase the ...

  • Satellite images make it possible to monitor ice break-up in Torne River

    SMHI has used high-resolution satellite images for the first time to monitor ice break-up in Torne River, one of Sweden’s largest unregulated rivers. The CryoLand research project has developed a method of identifying ice jams in the Torne River and flooded areas around the river using high-resolution satellite images. “Radar satellite images with a resolution of 1-3 ...

  • US Geological Survey awards satellite contracts for environmental monitoring

    The United States Geological Survey (USGS) announced the award of three multi-year acquisition contracts for high and moderate-resolution satellite imagery to GeoEye of Dulles, VA, DigitalGlobe of Longmont, CO and SPOT Image Corporation of Chantilly, VA. The contracts will to provide the USGS and other Federal agencies access to commercial satellite data from the US and international marketplace ...

  • New generation of Chinese environmental monitoring satellite now in orbit

    China has successfully launched the first of its new generation of polar-orbiting meteorological satellites, Fengyun-3A. Fengyun-3A was launched on 27 May 2008 from Taiyuan satellite launch centre in Shanxi Province of China. The payload of this new generation spacecraft is comprised of a complex suite of instruments including visible and infrared imagers, infrared and microwave sounders, a ...

  • How valuable are satellite observations of seawater quality?

    Global Earth Observation (GEO), such as satellite observations, helps manage environmental resources and prevent disasters. However, they are expensive. A recent study proposes a framework to assess the value of GEOs in which stakeholders are consulted. GEO consists of all observational information about the state of the world, including satellite observations and 'in situ' information. Many ...

  • NASA Prepares For Launch Of Next Earth Observation Satellite

    NASA's Landsat Data Continuity Mission (LDCM) is scheduled to launch Feb. 11 from Vandenberg Air Force Base in California. A joint NASA and U.S. Geological Survey (USGS) mission, LDCM will add to the longest continuous data record of Earth's surface as viewed from space. LDCM is the eighth satellite in the Landsat ...

  • Internationally coordinated use of satellites needed for managing floods

    Loss of satellites providing rainfall data could have a negative effect on global flood management, according to new research. However, this could be mitigated by improved international co-operation and the use of more modern satellite technology, the authors say. The study examined the consequences for flood management of the loss of four of the existing 10 dedicated rainfall measuring ...

  • Satellite Study Reveals Parched U.S. West Using Up Underground Water

    A new study by NASA and University of California, Irvine, scientists finds more than 75 percent of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States than previously thought. This study is the first to quantify the amount that ...

  • Glacier-melting debate highlights importance of satellites

    The intense public debate on how rapidly the Himalayan glaciers are retreating highlights the necessity for the constant monitoring of glaciers worldwide by satellites. Since glaciers are among the most reliable indicators of climate change and because they can have a major influence on water availability, knowledge of the recent changes and future behaviour is of great interest for climate ...

  • Satellites help Colombian fishermen chase fish

    Fishermen in Colombia will be able to tap into the latest satellite information to chase shoals of fish in their depleted fishing grounds. Using satellites from NASA — the US-based National Aeronautics and Space Administration — and the European Space Agency, researchers from the National University of Colombia identified chlorophyll hotspots, which indicate the presence of the ...

  • Promising results of environment monitoring satellite Jason-2 one week after launch

    One week has gone by since the launch, and everything is going very well with Jason-2. While the satellite is not yet in its final orbit (to be reached on 3 July), the first test measurements and calibrations have started. EUMETSAT, CNES, NASA and NOAA are cooperating to test every component of the ground segment, and results are looking very promising. The first Doris (Doppler Orbitography and ...

  • HORIBA Jobin Yvon Gratings in Sentinel-3A satellite helps monitor land and sea

To supply ...

  • Climate studies to benefit from 12 years of satellite aerosol data

    Aerosols, very small particles suspended in the air, play an important role in the global climate balance and in regulating climate change. They are one of the greatest sources of uncertainty in climate change models. ESA's GlobAerosol project has been making the most of European satellite capabilities to monitor them. Using data from the Along Track Scanning Radiometer-2 on the ERS-2 satellite, ...
