Sentences with phrase «satellite radar altimetry»

These missions - satellite radar altimetry projects overseen by the European Space Agency (ESA)- lasted from 1994 to 2012, providing the researchers plenty of data that could even be overlapped and compared to ensure an accurate assessment of ice shelf thickness for more than a decade.

To get the biggest picture now available, Paolo and his colleagues stitched together satellite radar altimetry data from three consecutive and overlapping missions: the European Space Agency's (ESA's) ERS - 1 and ERS - 2 (which flew from 1991 to 2000 and 1995 to 2011, respectively), and ESA's ENVISAT mission, which collected data from 2002 to 2012.

Not exact matches

Coastal altimetry, which provides detailed wave and sea level data in the coastal zone captured by specialist instruments called radar altimeters on board satellites, is at the heart of the project and scientists from NOC have been at the cutting - edge of this technique.

Indeed, satellite gravity data and radar altimetry reveal that the Totten Glacier of East Antarctica, which fronts a large ice mass grounded below sea level, is now losing mass [90].

Satellite radar altimetry, in which timing of a radar or laser beam return back to a satellite is used as a measure of surface elevation, enabled researchers to assess ice mass by examining elevation change over time.
