Wind Speed‐Up in Wind Farm Wakes Quantified From Satellite SAR and Mesoscale Modeling

Wind Energy, Volume 27, Issue 11, Page 1369-1387, November 2024.
ABSTRACT Satellite synthetic aperture radar (SAR) provides ocean surface wind fields at 10 m above sea level. The objective is to investigate the capability of SAR satellite StriX observations for mapping offshore wind farm wakes. The focus is on the conditions under which an apparent wind speed‐up is generated, measured in 48% of the 67 images ...

The Potential of Hydrogeodesy to Address Water‐Related and Sustainability Challenges

Water Resources Research, Volume 60, Issue 11, November 2024.
Abstract Increasing climatic and human pressures are changing the world's water resources and hydrological processes at unprecedented rates. Understanding these changes requires comprehensive monitoring of water resources. Hydrogeodesy, the science that measures the Earth's solid and aquatic surfaces, gravity field, and their changes over time ...

Vertical Carbon Export During a Phytoplankton Bloom in the Chukchi Sea: Physical Setting and Frontal Subduction

Journal of Geophysical Research: Oceans, Volume 129, Issue 11, November 2024.
Abstract In order to quantify pelagic‐benthic coupling on high‐latitude shelves, it is imperative to identify the different physical mechanisms by which phytoplankton are exported to the sediments. In June–July 2023, a field program documented the evolution of an under‐ice phytoplankton bloom on the northeast Chukchi shelf.

Toward Comprehensive Understanding of Air‐Sea Interactions Under Tropical Cyclones: On the Importance of High Resolution and Multi‐Modal Observations

Geophysical Research Letters, Volume 51, Issue 19, 16 October 2024.
Abstract The three‐dimensional structure of the Tropical Cyclone's baroclinic wake is synthesized as an averaged baroclinic‐dominant response of the upper ocean. The resulting persisting sea surface depression can easily be monitored using the present‐day altimeter constellation.

Advances in InSAR Analysis of Permafrost Terrain

Permafrost and Periglacial Processes, Volume 35, Issue 4, Page 544-556, October/December 2024.
ABSTRACT Differential interferometric synthetic aperture radar (InSAR) is a remote sensing technique for measuring surface displacements with precision down to millimeters, most commonly from satellites. In permafrost landscapes, InSAR measurements can provide valuable information on geomorphic processes and hazards, including thaw subsidence and frost

Recent velocity observations of Hubbard Glacier: A comparison of RADARSAT Constellation Mission with Sentinel-1, TerraSAR-X and RADARSAT-2 derived velocity maps to determine seasonal flow patterns

, 2023
Hubbard Glacier is an advancing tidewater glacier in Alaska, with large seasonal variations in flow speeds of 1500 to 5200 m a-1. The large size and fast speeds of Hubbard Glacier caused it to have possibly the largest rates of steady-state discharge of ...

Compact Polarimetry in Support of Lake Ice Breakup Monitoring: Anticipating the RADARSAT Constellation Mission

Canadian Journal of Remote Sensing, 2015
Abstract. Canada's RADARSAT Constellation Mission (RCM) will have the capacity to acquire C-band compact polarimetry (CP) data in all imaging modes over swaths up to 500 km wide. Our study aimed to assess and develop the utility of RCM CP data for the purpose of lake ice breakup monitoring.
