Retrieval of Effective Correlation Length and Snow Water Equivalent from Radar and Passive Microwave Measurements

open access: yesRemote Sensing, 2018
Current methods for retrieving SWE (snow water equivalent) from space rely on passive microwave sensors. Observations are limited by poor spatial resolution, ambiguities related to separation of snow microstructural properties from the total snow mass ...

Rain on snow (ROS) understudied in sea ice remote sensing: a multi-sensor analysis of ROS during MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) [PDF]

open access: yesThe Cryosphere, 2022
Arctic rain on snow (ROS) deposits liquid water onto existing snowpacks. Upon refreezing, this can form icy crusts at the surface or within the snowpack.

Best Practices in Crafting the Calibrated, Enhanced-Resolution Passive-Microwave EASE-Grid 2.0 Brightness Temperature Earth System Data Record

open access: yesRemote Sensing, 2018
Since the late 1970s, satellite passive-microwave brightness temperatures have been a mainstay in remote sensing of the cryosphere. Polar snow and ice-covered ocean and land surfaces are especially sensitive to climate change and are observed to ...

Definition differences and internal variability affect the simulated Arctic sea ice melt season [PDF]

open access: yesThe Cryosphere, 2019
Satellite observations show that the Arctic sea ice melt season is getting longer. This lengthening has important implications for the Arctic Ocean's radiation budget, marine ecology and accessibility.

All-passive microwave-diode nonreciprocal metasurface

open access: yesCommunications Physics, 2023
Breaking reciprocity in the microwave frequency range is strongly desirable in the development of modern electronic systems, as it enables nonreciprocal wave absorbing, nonreciprocal beam steering, frequency conversion, and protection of sensitive ...
