Wintertime Emissivities of the Arctic Sea Ice Types at the AMSR2 Frequencies

Remote Sensing, 2022
The surface effective emissivities of Arctic sea ice are calculated using Advanced Microwave Scanning Radiometer 2 (AMSR2) measurements. These emissivities are analyzed for stable winter conditions during the months of January–May and November and ...

Parameterization of the freeze/thaw discriminant function algorithm using dense in-situ observation network data

International Journal of Digital Earth, 2019
The near-surface soil freeze–thaw (FT) transition is an important factor affecting land-atmosphere exchanges, hydrology and carbon cycles. Thus, effectively monitoring the temporal–spatial changes of soil FT processes is crucial to climate change and ...

Retrieving Snow Depth Information From AMSR2 Data for Qinghai–Tibet Plateau

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Passive microwave data have been extensively used for snow depth (SD) inversion, but their accuracy has large error in the Qinghai-Tibet Plateau (QTP). Thus, there is still room for improvement in regional SD inversion.

Evaluation of Remotely Sensed Inundation Data Sets to Estimate Flood-Associated Emergency Department Visits After Hurricane Harvey. [PDF]

Geohealth
Abstract Floods can increase the risk of adverse health outcomes through multiple pathways, including contamination of food and water. Remotely sensed (RS) inundation extents can help identify regions with expected heightened flood‐related health risks, but variations across inundation data sets and their integration into health risk assessments may ...

Validation of Four Satellite-Derived Soil Moisture Products Using Ground-Based In Situ Observations over Northern China

Remote Sensing, 2022
Accurately obtaining the spatial distribution of soil moisture and its variability are the basis for the land-atmosphere interaction study. We investigated the fidelity of four satellite-based soil moisture products (AMSR2, CCI, SMAP, and SMOS) using in ...

AMSR2 all-sky radiance assimilation and its impact on the analysis and forecast of Hurricane Sandy with a limited-area data assimilation system

Tellus: Series A, Dynamic Meteorology and Oceanography, 2016
A method to assimilate all-sky radiances from the Advanced Microwave Scanning Radiometer 2 (AMSR2) was developed within the Weather Research and Forecasting (WRF) model's data assimilation (WRFDA) system.

Enabling Under Ice Glider Operations: A Backseat Driver Approach

Journal of Field Robotics, EarlyView.
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.
