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.
