Satellite mapping of the Antarctic gravity field

open access: yesAnnals of Geophysics, 1999
The production and analysis of the Antarctic digital magnetic anomaly map will be greatly aided by complementary gravity data. They help to constrain thickness variations of the crust and related magnetic effects that may be used for correcting long ...

Retrieval of Snow Depth on Arctic Sea Ice From Surface‐Based, Polarimetric, Dual‐Frequency Radar Altimetry

open access: yesGeophysical Research Letters, 2023
Snow depth on sea ice is an Essential Climate Variable and a major source of uncertainty in satellite altimetry‐derived sea ice thickness. During winter of the MOSAiC Expedition, the “KuKa” dual‐frequency, fully polarized Ku‐ and Ka‐band radar was ...

CryoSat Long-Term Ocean Data Analysis and Validation: Final Words on GOP Baseline-C

open access: yesRemote Sensing, 2023
ESA’s Earth explorer mission CryoSat-2 has an ice-monitoring objective, but it has proven to also be a valuable source of observations for measuring impacts of climate change over oceans.

Liquid filled canyons on Titan [PDF]

open access: yes, 2016
In May 2013 the Cassini RADAR altimeter observed channels in Vid Flumina, a drainage network connected to Titan’s second largest hydrocarbon sea, Ligeia Mare. Analysis of these altimeter echoes shows that the channels are located in deep (up to ~570 m),

Estimation of River Discharge Solely from Remote-Sensing Derived Data: An Initial Study Over the Yangtze River

open access: yesRemote Sensing, 2018
A novel approach has been developed to estimating river discharge solely using satellite-derived parameters. The temporal river width observations from Moderate Resolution Imaging Spectroradiometer (MODIS), made at two stream segments a distance apart ...

Parameter estimation for peaky altimetric waveforms [PDF]

open access: yes, 2013
Much attention has been recently devoted to the analysis of coastal altimetric waveforms. When approaching the coast, altimetric waveforms are sometimes corrupted by peaks caused by high reflective areas inside the illuminated land surfaces or by the ...

Canopy and Terrain Height Retrievals with ICESat-2: A First Look

open access: yesRemote Sensing, 2019
NASA’s Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) launched in fall 2018 and has since collected continuous elevation data over the Earth’s surface. The primary scientific objective is to measure the cryosphere for studies related to
