Temperature Effects in AMSR2 Soil Moisture Products and Development of a Removal Method Using Data at Ascending and Descending Overpasses

Remote Sensing
Soil moisture is among the most essential variables in hydrology and earth science. Many satellite missions, such as AMSR-E/2, have been launched to observe it in broader spatial coverage to overcome the shortage of in situ observations.

Habitat Selection and Intrapopulation Spatial Segregation in an Arctic Top Predator at the Southern Limit of Its Range

Global Change Biology, Volume 32, Issue 9, September 2026.
Located at the southern extent of the species' range, polar bears in James Bay exhibited intrapopulation variation in space use, resulting in two spatial clusters during the on‐ice season. Some bears remained within southern James Bay, whereas others ranged more broadly north of the bay.

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.

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 ...

Anomalous Sea Ice Retreat in the Refreezing Western Arctic by a 30‐Year Record Cyclone in October: Oceanic, Atmospheric, and Wave Influences

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract An extreme Arctic cyclone (AC) in October 2022 reached a record‐low pressure of 955 hPa and caused unusual wave‐induced sea‐ice breakup in the Canada Basin, making it the strongest event in the western Arctic in 30 years. Here we examine how this event interrupted freeze‐up by quantifying sea‐ice retreat associated with atmospheric and oceanic

Enabling Under Ice Glider Operations: A Backseat Driver Approach

Journal of Field Robotics, Volume 43, Issue 5, Page 3292-3311, August 2026.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.

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 ...

Cross-calibration between MWRI and AMSR2 to improve consistency of snow depth products

Research in Cold and Arid Regions
The Microwave Radiation Imager (MWRI), boarded on the FY-3 series satellites: FY-3B, FY-3C, and FY-3D, is the first satellite-based microwave radiometer in China, commencing passive microwave brightness temperature data acquisition since 2010.

Assimilation of All‐Sky TROPICS Constellation Radiance Data in the NASA Goddard Earth Observing System (GEOS)

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract This study examines the impact of assimilating all‐sky microwave radiances from the Time‐Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission within the NASA Global Earth Observing System (GEOS) data assimilation and forecasting framework based on the Gridpoint Statistical ...
