Generative Supervised Classification Using Dirichlet Process Priors. [PDF]

, 2010
Choosing the appropriate parameter prior distributions associated to a given Bayesian model is a challenging problem. Conjugate priors can be selected for simplicity motivations.

Observation and Coordination Needs for Current, Near‐Future, and Next Generation Earth‐Observing SAR Systems

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract This paper summarizes an evaluation by experts of how coordination of Earth‐observing Synthetic Aperture Radar (SAR) missions among the world's space agencies could advance toward game‐changing scientific discoveries and fully realizing SAR's practical capability to address many issues facing society.

Airborne Radar Reveals Area‐Wide Decadal Increase of Surface Mass Balance on the Plateau in Dronning Maud Land, East Antarctica

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Projections of Antarctica's sea‐level contribution depend on future changes in surface mass balance (SMB), yet it remains uncertain whether climate change has already impacted SMB on the East Antarctic Plateau, given diverging trends in prior studies.

Sea state bias in altimeter sea level estimates determined by combining wave model and satellite data [PDF]

, 2010
This study documents a method for increasing the precision of satellite-derived sea level measurements. Results are achieved using an enhanced three-dimensional (3-D) sea state bias (SSB) correction model derived from both Jason-1 altimeter ocean ...

Backwater Effects From River Ice Jams Observed With SWOT Pixel Cloud Data

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract This study examines the backwater effects from ice jams in Arctic rivers using the Surface Water and Ocean Topography (SWOT) satellite. Ice jams occur when chunks of ice accumulate and obstruct the river flow, causing rapid water level rises and flooding.

Greenland Ice Sheet surface roughness from Ku- and Ka-band radar altimetry surface echo strengths [PDF]

The Cryosphere
Surface roughness is an important factor to consider when modelling mass changes at the Greenland Ice Sheet (GrIS) surface (i.e., surface mass balance, SMB).

The Impact of Altimetry Corrections of Sentinel-3A Sea Surface Height in the Coastal Zone of the Northwest Atlantic

Remote Sensing, 2023
Corrections to altimeter-measured sea surface height anomalies (SSHA) have a larger proportional effect for synthetic aperture radar (SAR) altimetry than conventional, pulse-limited altimetry because of lower range noise.

Global River Radar Altimetry Time Series (GRRATS): new river elevation earth science data records for the hydrologic community

Earth System Science Data, 2019
. The capabilities of radar altimetry to measure inland water bodies are well established, and several river altimetry datasets are available. Here we produced a globally distributed dataset, the Global River Radar Altimeter Time Series (GRRATS), using ...

Mesoscale Eddy Currents Reshape the Spatial Distribution of Wave Height in the Southern Ocean

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mesoscale eddy currents influence ocean surface waves, but their imprints on wave height remain poorly described by observations. Here, we examine significant wave height (SWH) variations associated with more than 42,000 mesoscale eddies in the Southern Ocean using along‐track Jason‐3 altimeter measurements.
