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]

The 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

Remote 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 ...

Nonreciprocal Microwave Transmission in a Passive-Active Double-Cavity-Magnon System

IEEE Photonics Journal
We propose a scheme to realize nonreciprocal microwave transmission in a double-cavity-magnon system, which comprises a ferromagnetic yttrium iron garnet (YIG) sphere placed inside a passive microwave cavity coupled to another active cavity.

Distortion mechanisms in varactor diode-tuned microwave filters [PDF]

, 2006
This paper examines the broadband distortion behavior in flexible filters employing varactor-diode tuning elements. Series- and parallel-resonant varactor-loaded transmission-lines, both commonly used in bandpass and bandstop microwave filters, are ...
