South Korea's space agency has joined its international counterparts in putting satellite data at the disposal of rescue authorities following major disasters such as earthquakes and tsunamis. The Korea Aerospace Research Institute (KARI), under the Ministry of Education, Science and Technology, formally became the newest member of the International Charter "ËœSpace and Major Disasters' on 7 July. Founded by ESA and the French space agency, CNES, the Charter is an international...

A NASA-led research team has used a variety of NASA satellite data to create the most precise map ever produced depicting the amount and location of carbon stored in Earth's tropical forests. The data are expected to provide a baseline for ongoing carbon monitoring and research and serve as a useful resource for managing the greenhouse gas carbon dioxide. The new map, created from ground- and space-based data, shows, for the first time, the distribution of carbon stored in forests across more...

An ESA project has recently demonstrated that new ways of processing satellite data can show how different properties of snow can be observed from space. This new method is expected to lead to a much deeper understanding of the role snow plays in the Earth system. Snow is a fundamental component of Earth's energy and water cycles. It plays an important role reflecting solar radiation back out to space, emits heat and holds a significant percentage of the global freshwater budget. However,...

Punxsutawney Phil predicted that spring will come on time, and NASA satellite data suggests that residents in more than one-third of the U.S. are now anxious for the prediction to come true.A massive winter storm touched 30 states over the last couple of days, including Phil's home at Gobbler's Knob in Punxsutawney, Pa. where rain mixed with sleet and freezing rain this morning before it changed to snow as part of that system. Phil's town is about 80 miles northeast of Pittsburgh. Looking at...

We may be becoming an ever more technologically advanced society, but we remain as dependent as ever -- if not more and more so -- on the natural world that surrounds us. That is one takeaway from new NASA research that has found humans are using an increasing amount of the Earth's total land plant production each year for food, fiber, building and packaging materials and biofuels. This remains a young data record, as one of the first global measurements tied to satellite data was published...

Since its latest series of deadly eruptions, Java's Mt Merapi has been spewing volcanic ash clouds into the air. Satellite data are crucial for assessing the eruption's danger to air traffic and public safety. Mt Merapi began erupting on 26 October and has killed more than 200 people. Numerous international flights in and out of the Indonesia area have been cancelled due to ash clouds. Flying through such clouds is a threat to safety because the damaging particles can lead to engine...

Taking advantage of NASA's 'Operation Ice Bridge' campaign, measurements of Arctic sea ice have been made from an aircraft flying directly under CryoSat-2's orbital path. These measurements offer an early opportunity to check the quality of the newly launched CryoSat-2 satellite data over sea ice. Following the launch of ESA's CryoSat-2 ice mission April 8, the satellite's Synthetic Aperture Interferometric Radar Altimeter (SIRAL) was switched on and delivered its first radar echo data on...

NASA scientists analyzing 30 years of satellite data have found that the amount of ultraviolet (UV) radiation reaching Earth's surface has increased markedly over the last three decades. Most of the increase has occurred in the mid-and-high latitudes, and there's been little or no increase in tropical regions. The new analysis shows, for example, that at one line of latitude "” 32.5 degrees "” a line that runs through central Texas in the northern hemisphere and the country of...

As rescue workers scramble to provide assistance to hundreds of thousands of people following Haiti's earthquake, Earth observation satellite data continues to provide updated views of the situation on the ground. Following the 7.0-magnitude earthquake that hit Haiti on January 12, international agencies requested satellite data of the area from the International Charter on 'Space and Major Disasters'. The Charter, an international initiative aimed at providing satellite data free of charge...

A new system from an Italian company uses weather satellite data to estimate the potential of solar cell power plants and monitor their performance. The approach helps to give a faster return on investments in clean solar energy. Solar cells have been used for many years to power pocket calculators and, more recently, street signs, garden lighting and other small devices. But since the need for sustainable living has become a key issue in our society, there has been a considerable increase in...
