Earth Networks Part 3
2013-04-08 08:46:14

Part 3 of redOrbit´s exclusive 6-part series Alan McStravick for redOrbit.com - Your Universe Online In the last installment of this series, we took a close-up look at the technology behind Earth Networks Total Lightning Network (ENTLN). In part 3, we will look at the rate of false alarms put out by the ENTLN and compare those to the warning system utilized by the National Weather Service (NWS). We will also look at an anecdotal situation where Robert Marshall, CEO of Earth...

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...

Ups And Downs Of The Norwegian Sea
2012-11-20 09:57:08

ESA An anticlockwise rotation of sea-surface height patterns has been observed near Norway´s west coast. Archived data from radar altimeters on the ERS-1, ERS-2 and Envisat satellites show the wave-like motion around the center of the Lofoten Basin. The Lofoten Basin is a topographic depression about 3500 m deep in the Norwegian Sea and plays an important role in sustaining global ocean circulation. It is a transit area for the warm and saline Atlantic Water on its way to the...

'20 Years Of Progress In Radar Altimetry Symposium' Gains Altitude In Venice
2012-09-24 10:41:43

Scientists have gathered in the 'floating city' this week to talk about radar altimetry — measuring the heights of the global sea surface, freshwater bodies, land and ice using spaceborne sensors. Held every five years, the '20 Years of Progress in Radar Altimetry Symposium' gives participants the opportunity to focus on the challenges overcome to develop our current understanding of Earth´s surface variations observed by altimetry. Radar altimeters record the surface...

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...
