Supporting Data: Characterizing Sub-Glacial Hydrology Using Radar Simulations

Raw data from "A Simulation Approach to Characterizing Sub-Glacial Hydrology". THW2_UBH0c_X243a.M1D1 is the 1 dimensionally focused, high gain radargram from the IPR radar survey. Actual along-track IPR pick data for THW2_UBH0c_X243a are contained in file X243a_rad_data_foc.csv. Metadata are as follows: pst: flight line name long: observation longitude in decimal degrees (EPSG:4326) lat: observation latitude in decimal degrees (EPSG:4326) bed: bed pick elevation in [m] year: timestamp year day: timestamp day t_ms: timestamp miliseconds srf: surface pick elevation in [m] echo: bed echo strength [dB] thk: ice thickness [m] Lice: estimated 2-way attenuation loss [dB] R_bed: bed absolute reflectivity [dB] L_unc: 2-way attenuation loss uncertainty [dB] Simulated data: A folder for each simulation contains the files listed below. Inputs: [INPUT] Trajectory_MRS.mat: values for simulated aircraft trajectory, including total # of rangelines (TrackLengthTot), aircraft position at each rangeline in [m] (sc_position_x, sc_position_y, sc_position_z), and aircraft velocity in [m/s] (sc_vel_x, sc_vel_y, sc_vel_z) bed.csv: lists all z-values in [m] for the bed surface chan.csv: lists all z-values in [m] for the channel surface params.txt: lists all pertinent parameters from the simulation surf.csv: lists all z-values in [m] for the ice surface xx.csv: lists all x-values in [m] for the ice surface xx_b.csv: lists all x-values in [m] for the bed and channel surface yy.csv: lists all y-values in [m] for the ice surface yy_b.csv: lists all y-values in [m] for the bed and channel surface Radargrams: RgramFocPWR_RM3_hamm.mat: Focused radargram power [dB] RgramRawPWR.mat: Raw radargram power [dB] RgramRCPWR.mat: Range-compressed radargram power [dB]
