1. Satellite Radar Altimetry for Determination of Geoid Undulations and Gravity Anomalies
Sammanfattning : The sea level changes both temporally (due to dynamic effects) and spatially (due to sea bottom topography and inhomogeneities in the Earth's crust). Satellite radar altimetry is a remote sensing technique which can be used for e.g. determination of the instantaneous and mean sea level, and gravity anomalies at sea. LÄS MER
2. Detection and classification of sea ice from spaceborne multi-frequency synthetic aperture radar imagery and radar altimetry
Sammanfattning : The sea ice cover in the Arctic is undergoing drastic changes. Since the start of satellite observations by microwave remote sensing in the late 1970's, the maximum summer sea ice extent has been decreasing and thereby causing a generally thinner and younger sea ice cover. LÄS MER
3. Monitoring Water Availability in Northern Inland Waters from Space
Sammanfattning : River deltas and lakes support biodiversity and offer crucial ecosystem services such as freshwater provision, flood control, and fishing. However, climate change and human activities have affected deltas and lakes globally, altering the services they provide. LÄS MER
