The importance of global and frequent data coverage of volcanoes was highlighted in a recent article published in Science. Satellites are finding that volcanoes previously thought to be dormant are showing signs of unrest.
Recent studies show that satellite radar data can be exploited to map forest height, 3D forest structure and their natural or anthropogenic disturbance with high spatial resolution and accuracy.
In the early hours of 1 March 2002, the largest Earth observation satellite ever built soared into orbit from ESA’s launch base in Kourou, French Guiana. For a decade, Envisat has been keeping watch over our planet.
With missions scheduled throughout the year, 2012 is shaping up to be an extraordinary time for NASA’s Airborne Science Program and Earth system science research.
Scientists are making advances in the use of satellite data to map changes in Earth’s surface. Subsidence of only millimeters can be detected thanks to advances in technology.
