Larsen C Ice Shelf in the Western Weddell Sea is a Hotspot for Export Production in the Antarctic Ocean

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract The Southern Ocean accounts for >30% of the global ocean CO2 sink as a result of its solubility and biological pumps. To investigate the biological pump near Larsen C Ice Shelf (LCIS) in the Southern Ocean's western Weddell Sea, we measured the concentrations and nitrogen isotope ratios of nitrate, ammonium, and particulate organic nitrogen ...

Global Land Surface Emissivity Estimation From AMSR2 Observations

IEEE Geoscience and Remote Sensing Letters, 2016
A reliable estimate of emissivity is critical for a wide range of applications for the atmosphere, the biosphere, the lithosphere, the cryosphere, and the hydrosphere. This study uses three years (August 2012 to July 2015) of data from the Advanced Microwave Scanning Radiometer-2 sensor that is onboard the Global Change Observation Mission 1st Water ...

Joint assimilation of SMAP soil moisture and AMSR2 vegetation optical depth retrievals into the Noah-MP land surface model

, 2023
As soil moisture and vegetation water content both affect the emissivity from the land surface, each of them can be derived from satellite-based passive microwave measurements. In this study, we use soil moisture retrievals from the 36 km SMAP L2 product

Evaluation of a New Merged Sea-Ice Concentration Dataset at 1 km Resolution from Thermal Infrared and Passive Microwave Satellite Data in the Arctic

Remote Sensing, 2020
Sea-ice concentration (SIC) data with fine spatial resolution and spatially continuous coverage are needed, for example, for estimating heat fluxes. Passive microwave measurements of the Advanced Scanning Microwave Radiometer 2 (AMSR2) offer spatial ...

Synoptic Controls of Extreme Ice Area Flux Events Along Nares Strait

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Nares Strait, the channel between Ellesmere Island and northwest Greenland, connects the Arctic Ocean's Lincoln Sea to northern Baffin Bay. The transport of thick, multi‐year sea ice southward down the Strait contributes to the overall loss of this important ice class from the Arctic.

Improvement of AMSR2 Soil Moisture Products Over South Korea

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2017
Soil moisture (SM) is a critical parameter for interpreting the status of land surfaces and vegetation because it has an important role in the exchange of water and heat energy between the land surface and atmosphere. SM can be retrieved with satellite microwave sensors, which offer several advantages in that they are cost-effective, give rapid results,

Winter‐to‐Winter Sea Surface Temperature Anomaly Reemergence in the Yellow Sea

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract The reemergence of winter sea surface temperature anomalies (SSTAs) serves as an effective oceanic memory mechanism, linking winter SSTs across consecutive years in mid‐latitude deep oceans. However, its existence and potential role in modulating SSTA variability in continental shelf seas have remained largely unexplored.

ASTRA: AMSR2-to-SMAP Image-to-Image TRAnslation for soil moisture conversion and radiative transfer model-based interpretation

International Journal of Applied Earth Observations and Geoinformation
Soil moisture (SM) plays a central role in regulating land–atmosphere exchanges of water and energy and is therefore essential for climate and hydrological studies.
