Record #101138:
Radar altimeter ground truth measurements in Antarctica - 90° South Expedition / Anon.
Title: | Radar altimeter ground truth measurements in Antarctica - 90° South Expedition / Anon. |
Date: | 1989. |
In: | Earth Observation Quarterly. (1989.), (26) (1989) |
Abstract: | Expedition conducted glaciological field experiments, including measurement of return microwave signals from various ice surfaces, summer 1986-87. Concluded that radar altimeter signals over ice sheet may give widely differing height estimates because of varying reflectivity values for different types of surface and it was necessary to perform in-situ calibration measurements on these different surfaces. Support data (crystal structure, moisture content, temperature) should be collected for different types of snow and ice. |
Notes: | Earth Observation Quarterly. (26) :[1-3] (1989). |
