ICESat-2 now has its very own web site

ICESat-2 will provide scientists with height measurements that create a global portrait of Earth’s 3rd dimension, gathering data that can precisely track changes of terrain including glaciers, sea ice, forests and more.

While many of ICESat-2’s discoveries are yet to be imagined, the satellite mission has four science objectives:

  • Measure melting ice sheets and investigate how this effects sea level rise,
  • Measure and investigate changes in the mass of ice sheets and glaciers,
  • Estimate and study sea ice thickness,
Measure the height of vegetation in forests and other ecosystems worldwide.[/li]

(I'm not aware of thread dedicated to satellites... so hopefully Jim will let me use this one.)

EGU Blogs » Divisions » Cryospheric Sciences » Image of the Week – The Gap, the Bridge, and the Game-changer

The Gap, the Bridge, and the Game-changer are three series of satellites. They carry instruments that measure the microwave radiation emitted by the Earth (called passive microwave instruments), while flying 800 km above our heads at 7,5 km/s. Since the late 1970s, most sea ice properties (concentration, extent, area, velocity, age and more!) have been measured with such passive microwave instruments.
So who are the Gap, the Bridge, and the Game-changer? Their story is what this Image of the Week is about…
