European Storm Surge Measured By CryoSat
2013-12-09 12:58:42

ESA ESA’s CryoSat satellite measured the storm surge from the recent North Sea storms, as high waters passed through the Kattegat sea between Denmark and Sweden. During 5–6 December, a major storm passed through northern Europe causing flooding, blackouts, grounding flights and bringing road, rail and sea travel to a halt. Since the storm coincided with a period of high tides in the North Sea, there were extremely high sea levels – a ‘storm surge’. In the UK, sea levels...

Europe's CryoSat Mission Gives Scientists Better Look At Earth's Ice
2012-12-21 14:14:19

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency's (ESA) ice mission is giving scientists a better look at oceans, coastal areas, inland water bodies and land. The orbiting CryoSat launched in 2010 and was developed to measure the changes in the thickness of polar sea ice, the elevation of ice sheets that blanket Greenland and Antarctica, and mountain glaciers. The satellite's radar altimeter not only detects tiny variations in the height of the...

A rain of navigation signals falls constantly upon the Earth from GPS and the initial satellites in Europe's Galileo system, enabling an ever-increasing number of positioning and guidance services. Afterwards these microwave beams bounce back to space "“ where a proposed ESA mission aims to harness them as a scientific resource and explore their potential for terrestrial remote sensing applications. Intercepting reflected satnav signals and calculating their travel time is a way to...

A radar altimeter measures altitude above the terrain beneath an aircraft as opposed to a barometric altimeter which provides the distance above a pre-determined datum, usually sea level. Radar is the underpinning principle of the system. Radio waves that are reflected back from the ground are timed in order to calculate speed, distance, and time which are related to the each other and can be used to calculate the distance from one point to another. Lloyd Espenschied invented the radar...
