Assimilation of ice and water observations from SAR imagery to improve estimates of sea ice concentration [PDF]

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2015
In this paper, the assimilation of binary observations calculated from synthetic aperture radar (SAR) images of sea ice is investigated. Ice and water observations are obtained from a set of SAR images by thresholding ice and water probabilities ...

Interference mitigation in passive microwave radiometry [PDF]

open access: yesIEEE International Geoscience and Remote Sensing Symposium, 2003
Relentless development of the microwave spectrum for telecommunications and other active services enhances the risk of anthropogenic interference to the passive Earth Exploration Satellite Service (EESS). While spectral allocation remains the primary basis for avoiding interference between the passive and active services, it is also prudent to consider

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 ...
