dc.description.abstract | The usefulness of accurate, fine resolution accumulation layer measurements over central Greenland and West Antarctica is significant for the improvement of ice sheet models. These models are critical to both global climate models as well as understanding sea level rise. Previously developed accumulation layer radars were used as templates for the current single channel system. Improvements were incorporated including increased output power, increased receiver sensitivity, single antenna operation, and reduced susceptibility to external noise sources. Steps were also taken to reuse previously purchased components to reduce development costs. Externally developed Vivaldi and elliptical dipole antennas were utilized. Collected data shows the system is capable of measuring layering to a depth of nearly 300 m in most dry snow regions of Greenland and West Antarctica with a resolution of ~0.5 m. Future revisions will focus on reducing size and weight, as well as incorporate multiple receive channels to allow for clutter rejection algorithms to be applied; this will allow for viable data collection in percolation and wet snow zone of major ice sheets. | |
