Scattering Physics in Microwave Signatures of Sea Ice: A Focussed Investigation.

Abstract

The goals of this work have been (1) to achieve a clear, quantitative understanding of the scattering physics behind microwave signatures of geophysically important sea ice types, and (2) to derive microwave remote sensing methods based on, and taking full advantage of, this understanding. We have worked to understand quantitatively the scattering physics and signature statistics in three important thin ice types that are simulated in the CRRELEX experiment. Specifically, these are bare and snow-covered congelation ice, as well as frazil/pancake ice. In accord with the aims of the Sea Ice Electromagnetics Accelerated Research Initiative, we have also initiated collaboration with investigators in the inverse-modeling community. Specifically, we are helping to develop new inversion methods applicable in the case of electromagnetically-lossy media such as sea ice (in collaboration with J. Sylvester). We have begun to apply these methods to vertical incidence wideband microwave reflectivity data acquired as part of the CRRELEX experiment.
