QUALITY ASSESSMENT OF AN EXTENDED INTERFEROMETRIC RADAR DATA PROCESSING APPROACH [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Radar data acquisition is a reliable technology to provide base data for topographical mapping. Its flexibility and weather independency makes radar data more attractive in comparison with traditional airborne data acquisition.

Airborne polarimetric Doppler weather radar: Trade-offs between various engineering specifications [PDF]

2016 IEEE International Symposium on Phased Array Systems and Technology (PAST), 2016
NCAR/EOL is investigating potential configurations for the next generation airborne phased array radar (APAR) that is capable of retrieving dynamic and microphysical characteristics of clouds and precipitation. A number of antenna aperture configurations, and signal processing algorithms will be used for realizing overall performance of the APAR.

Remote sensing and geospatial analysis for the study of plant community regeneration in human‐modified landscapes

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Natural regeneration is essential for maintaining functionally diverse and resilient plant communities in human‐modified landscapes. To design and implement successful conservation and restoration initiatives in these landscapes, research on the environmental and anthropogenic drivers of natural regeneration must be scaled up beyond ...

Modeling the Amplitude Distribution of Radar Sea Clutter

Remote Sensing, 2019
Ship detection in the maritime domain is best performed with radar due to its ability to surveil wide areas and operate in almost any weather condition or time of day.

High‐resolution LiDAR and stereo‐DEMs for debris flow analysis in the Western Ghats, India: Sediment volume computation and run‐out modeling

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
The 2020 Pettimudi debris flow in the Western Ghats of India killed 70 people. Our study using stereo‐DEM, UAV‐based LiDAR data, and field data estimated the sediment loss as 17 × 104 m3. Abstract Computation of sediment volume and accurate modeling of run‐out using high‐resolution digital elevation models (DEMs) are essential for assessing debris flow

Drilling Within the Critical Zone

Hydrological Processes, Volume 40, Issue 3, March 2026.
This review synthesises 30 years of critical zone drilling methodologies for studying subsurface weathering, water storage, and biogeochemical processes. We evaluate drilling techniques, sampling strategies, downhole logging, and long‐term monitoring approaches while addressing contamination control and core preservation challenges.

Detecting Snow Avalanche Activity Using Infrasound: Hooker Valley, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Snow avalanches pose considerable hazards to people and infrastructure in alpine environments. Traditional avalanche monitoring relies on meteorological data and visual observations, which can be limited in scope and timeliness. Infrasound offers a promising complementary monitoring tool by detecting the low‐frequency sound waves generated by ...

Segmentation of Oil Spills on Side-Looking Airborne Radar Imagery with Autoencoders

Sensors, 2018
In this work, we use deep neural autoencoders to segment oil spills from Side-Looking Airborne Radar (SLAR) imagery. Synthetic Aperture Radar (SAR) has been much exploited for ocean surface monitoring, especially for oil pollution detection, but few ...

Spatial Variability of Sea State in the German Bight and Influence of Offshore Wind Farms

Wind Energy, Volume 29, Issue 3, March 2026.
ABSTRACT Offshore wind farms are growing worldwide and increase the source of renewable energy. However, as the extent and density of offshore wind farms increase, there is growing importance to understand the interactions with physical systems and the marine environment, in particular, the sea state.

Processes Driving Drift‐Ice Evolution and Its Interaction With the Oceanic and Atmospheric Boundary Layers

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Sea ice is a crucial component of polar climate systems and is undergoing substantial changes in both hemispheres due to evolving climatic conditions. Arctic sea ice is transitioning from perennial to seasonal cover, and the Southern Ocean sea ice is exhibiting recent minima and enhanced seasonality.
