Remote sensing of sea ice: advances during the DAMOCLES project [PDF]

The Cryosphere, 2012
In the Arctic, global warming is particularly pronounced so that we need to monitor its development continuously. On the other hand, the vast and hostile conditions make in situ observation difficult, so that available satellite observations should be ...

Sea Surface Wind Measurement by Airborne Weather Radar Scanning in a Wide-Size Sector

Atmosphere, 2016
We suggest a conceptual approach for measuring the near-surface wind vector over water using the airborne weather radar, in addition to its standard meteorological and navigation applications.

Estimating Ocean Vector Winds and Currents Using a Ka-Band Pencil-Beam Doppler Scatterometer

Remote Sensing, 2018
Ocean surface currents and winds are tightly coupled essential climate variables, and, given their short time scales, observing them at the same time and resolution is of great interest.

Optimization of Airborne Antenna Geometry for Ocean Surface Scatterometric Measurements

Remote Sensing, 2018
We consider different antenna configurations, ranging from simple X-configuration to multi-beam star geometries, for airborne scatterometric measurements of the wind vector near the ocean surface.

Measurements of ocean wave spectra and modulation transfer function with the airborne two‐frequency scatterometer [PDF]

Journal of Geophysical Research: Oceans, 1985
The results of this research show that the directional spectrum and the microwave modulation transfer function (MTF) of ocean waves can be measured with the airborne two‐frequency scatterometer‐microwave resonance technique. By combining two‐frequency backscatter resonance intensity with estimates of the directional wave spectrum (obtained by the ...

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Estimating Submesoscale‐Driven Particulate Organic Carbon Flux From Remote Sensing at a Dynamic Upwelling Front

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Submesoscale (1–10 km) vertical velocities at fronts enhance the exchange of particulate organic carbon (POC) and heat between the surface ocean and depth. While POC and temperature can be readily assessed in situ, direct quantification of flux remains uncertain due to the observational challenges of measuring submesoscale vertical velocities ...

Ageostrophic Velocities of Curved Ocean Fronts

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Ageostrophic velocities at ocean fronts play a key role in ventilating the upper ocean. The overturning circulation driven by cross‐front ageostrophic flow is widely recognized as the major mechanism of vertical transport, but the role of along‐front ageostrophic velocities remains underrepresented in existing theory.

Sensitivity of Tropical Cyclone Forecasts to the Loss of Low Earth Orbit Satellite Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Tropical cyclones are among the most destructive natural hazards, impacting millions of people worldwide each year. Accurate and timely forecasts are therefore essential for effective preparedness and risk mitigation. Forecast skill depends on both the performance of numerical weather prediction models and the observations assimilated into the
