Distinctive Patterns of Water Level Change in Swedish Lakes Driven by Climate and Human Regulation

Water Resources Research
Despite having approximately 100,000 lakes, Sweden has limited continuous gauged lake water level data. Although satellite radar altimetry (RA) has emerged as a popular alternative to measure water levels in inland water bodies, it has not yet been used ...

Monitoring of water level of Lake Sarygamysh based on Earth remote sensing data

Водное хозяйство России: проблемы, технологии, управление
Lakes and the hydrological processes occurring within them are important indicators of global environmental and climatic transformations. Changes in lake water level and volume are closely linked not only to natural factors (precipitation, evaporation ...

Geodetic analysis of Skylab altimetry preliminary data - SL/2 EREP pass 9 [PDF]

The author has identified the following significant results. The analysis was based on a time series intrinsic relationship between the satellite ephemeris, altimeter measured ranges, and the corresponding a priori values of subsatellite geoidal heights.

Dynamic sea surface topography, gravity and improved orbit accuracies from the direct evaluation of SEASAT altimeter data [PDF]

A method for the simultaneous solution of dynamic ocean topography, gravity and orbits using satellite altimeter data is described. A GEM-T1 based gravitational model called PGS-3337 that incorporates Seasat altimetry, surface gravimetry and satellite ...

A Special Collection on Hydrogeodesy in a New Era of Satellites for Better Understanding and Management of Water Resources

Water Resources Research
Hydrogeodesy is the discipline that measures the Earth's solid and aquatic surfaces and gravity field from space to study water resources and their changes over time. The Special Collections on Hydrogeodesy: Understanding Changes in Water Resources Using

The analysis of temporal variations in regional models of the Sargasso Sea from GEOS-3 altimetry [PDF]

The dense coverage of short pulse mode GEOS-3 altimeter data in the western North Atlantic provides a basis for studying time variations in the sea surface heights in the Sargasso Sea.

Ku‐ and Ka‐Band Polarimetric Radar Waveforms and Snow Depth Estimation Over Multi‐Year Antarctic Sea Ice in the Weddell Sea

Geophysical Research Letters
Antarctic sea ice has seen recent rapid declines in extent, but it remains unclear whether this is accompanied by thinning. Due to the relative abundance and complexity of overlying snow on sea ice, radar altimetry methods routinely deployed for sea ice ...

Problem footprints in Magellan altimetry data [PDF]

The intensity, time-delay, and frequency content of radar echoes from the Magellan altimetry system are reduced to several parameters that are of great use in addressing many geological issues of the surface of Venus.
