Squinted SAR processed products for radioglaciology

This project was supported by NSF grant #2317927: Postdoctoral Fellowship: OPP-PRF: Disentangling Ice-sheet Internal and Basal Processes through Novel Ice-penetrating Radar Integration Built on Scalable, Cloud-based Infrastructure.

They were originally collected by the Center for Remote Sensing of Ice Sheets (CReSIS) as a part of Operation IceBridge. --- Instruments and DevicesData were collected with the CReSIS Multi-channel Coherent Radar Depth Sounder 3 (MCoRDS3) (Rodriguez-204Morales and others, 2013). --- Acquisition ProcedureFor this survey, MCoRDS was flown with a six-element antenna-array mounted in the cross-track direction under a DC8 airframe and operated across a 165–215 MHz frequency band. The surveyed area included both along- and across-flow (flux-gate) profiles for glaciers in the Filchner Ice Shelf drainage basin, East Antarctica. We emphasize two profiles from Academy Glacier. --- Data ProcessingAll data processing was done within the Open Polar Radar software package, with support from the University of Kansas, NASA grants 80NSSC20K1242 and 80NSSC21K0753, and NSF grants OPP-2027615, OPP-2019719, OPP-1739003, IIS-1838230, RISE-2126503, RISE-2127606, and RISE-2126468. New processing methods were introduced to the Open Polar Radar toolbox as a part of this project and used to create the output data files presented here.
