Hills, bhills@uw.edu --- Dataset Description These are ground-based radar data collected from a subglacial lake ~15 km from the geographic South Pole. All data provided here were collected between Dec. 24, 2018 and Feb. 4, 2019. Data were collected with a high-frequency (3 MHz) ice-penetrating radar system towed along the ice surface. This project was supported by NSF grant #1744649: Ice Dynamics at the Intersection of the West and East Antarctic Ice Sheets. --- Note for .mat files MATLAB is proprietary software, but .mat files can easily be opened with open source software such as Python.

Each radar_line .mat file contains the following 9 variables: x_polstere (1, #traces): Polar stereographic x coordinate, in meters. y_polstere (1, #traces): Polar stereographic y coordinate, in meters. latitude (1, #traces): Latitude grid longitude (1, #traces): Longitude grid elevation (1, #traces): The elevation of the ice sheet surface (relative to WGS84), in meters. distance (1, #traces): The along-track distance starting from 0, in meters. serial_date (1, #traces): Decimal days since year 0. travel_time (#samples, 1): Fast time since radar transmit pulse, in microseconds. radargram (#samples, #traces): The processed radar image. The processing flow is described in the manuscript cited above.
