  • USGS accelerates access to satellite data

    Federal and state agencies that need satellite imagery from commercial sources will find it much easier to acquire the data through a streamlined process managed by the U.S. Geological Survey. Many federal and state agencies rely on imagery of the earth acquired by commercial satellites to conduct missions related to natural hazard response, resource management, crop monitoring and climate change ...

  • 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 data improve aviation safety

    Thousands of planes are grounded across Europe due to the spread of volcanic ash following the recent eruption under Iceland's Eyjafjallajoekull glacier. Volcanic eruptions eject large amounts of ash and trace gases such as sulphur dioxide into the atmosphere, often reaching the altitudes of scheduled flights. When flying through a volcanic ash cloud, ash particles enter the jet engines which can ...

  • 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 ...

  • Methane: satellite data may improve emissions estimates

    Greenhouse gas (GHG) inventories are significantly underestimating methane emissions from a region in the southwest of the United States, and potentially elsewhere, a new study has found. The authors of the study suggest that satellite data could be used to identify and quantify new sources of methane, such as fracking.  Inventories of estimated GHG emissions, which are used by ...

  • Satellite data provide insight into melting Arctic ice

    In September 2012, the smallest ice spread to date in the Arctic was recorded. With data from satellites, scientists at SMHI have analysed changes in the atmosphere, and then compared the conditions for the ice melt in 2012 with 2007, the previous record low for ice spread. “Satellite-based monitoring of the atmosphere can be an important source of knowledge in predicting extreme ...

  • ESA satellites flying in formation

    Based on the outstanding success of the first tandem mission between ERS-2 and Envisat last year, ESA has paired the two satellites together again to help improve our understanding of the planet. ERS-2, ESA’s veteran spacecraft, and Envisat, the largest environmental satellite ever built, both carry Synthetic Aperture Radar (SAR) instruments that provide high resolution images of the Earth's ...

  • DNI satellite data truth? - How to handle the difference in values derived from different satellite data providers?

    Technical Top Tip courtesy of Solar Resource Assessment When it comes to CSP project evaluation, one of the biggest uncertainty factors for the performance is the available Direct Normal Irradiance (DNI) at the site. 1. DNI vs. GHI DNI distinguishes significantly from GHI (Global Horizontal Irradiance), which is more applicable for ...

  • 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 ...

  • 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, ...

  • Business, citizens and environment to benefit from free access to EU satellite data

    The European Commission will provide free, full and open access to a wealth of important environmental data gathered by Copernicus, Europe's Earth observation system. The new open data dissemination regime, which will come into effect next month, will support the vital task of monitoring the environment and will also help Europe's enterprises, creating new jobs and business opportunities. Sectors ...

  • NASA employs satellite data to calculate California`s carbon budget

    Calculating the greenhouse gas emissions from a city, state, or country is a tricky business, as the calculations must include comprehensive tabulations of energy use, land-use changes, industrial emissions, and other factors. However, a recent project from the National Aeronautics and Space Administration (NASA) may point the way towards a future, simpler way. NASA employed its Terra satellite ...

  • Detecting river floods using low-resolution satellite data

    The methodology for detecting river floods using Terra low-resolution data was developed and tested by specialists of the Risk Monitoring and Forecasting Section under the Fire and Civil Defense Department of the Volgograd Region (Russia) Administration. This year"s spring flood ...


  • Satellites unlock secret to vanishing water

    A team of hydrologists led by Matt Rodell of NASA's Goddard Space Flight Center in Greenbelt, Md., found that northern India's underground water supply is being pumped and consumed by human activities, such as irrigating cropland, and is draining aquifers faster than natural processes can replenish them. The results of this research were published today in Nature. The finding is based on data ...


  • ESA extends Envisat satellite mission

    ESA Member States have unanimously voted to extend the Envisat mission through to 2013. Envisat – the world’s largest and most sophisticated satellite ever built – has been providing scientists and operational users with invaluable data for global monitoring and forecasting since its launch in 2002. 'The decision to extend the Envisat mission operations, taken during the last ESA Earth ...

  • New climatology on clouds and radiation from weather satellite data

    The properties and distribution of clouds around the globe are important to climate research. There is now a 28-year compilation of clouds and radiation – a cloud climatology – based on data from polar satellites. The Earth’s climate is largely determined by incoming solar radiation. Clouds help to reflect some of the radiation away. “Roughly 30 per cent of the ...
