Integrating Microwave Remote Sensing with Physical Models to Reveal Melt Dynamics and Structural Variability in Queen Maud Land
Andreas Colliander, Nicole-Jeanne Schlegel, Alamgir Hossan, Catherine Walker et autres
The Queen Maud Land (QML) sector of East Antarctica comprises a complex system of grounded ice sheet and fringing ice shelves that regulate ice discharge to the Southern Ocean. Ice-sheet evolution in this region is controlled by interactions between atmospheric forcing, katabatic …

Andreas Colliander, Nicole-Jeanne Schlegel, Alamgir Hossan, Catherine Walker et autres
Abstract. Surface melt strongly influences the thermodynamics and stability of Antarctic ice shelves, yet firn models remain poorly constrained due to scarce observations. We present a framework that integrates satellite-borne microwave radiometry with firn modelling to evaluate meltwater generation and infiltration. Using …

Depth of Liquid Water Infiltration in Greenland Firn Based on L-Band Radiometry, a Snow Physics Model, and Machine Learning
Taylor D. Moon, J. T. Harper, Alamgir Hossan, Andreas Colliander
As melting of the firn layer across the Greenland Ice Sheet increases, determining the fate of infiltrating meltwater is crucial for assessing the evolution of the firn and its potential to buffer runoff. While L-band satellite radiometry can estimate the vertically integrated …
