What is the unit of output wavefield?

[tjk9501]

Hello, Dr. Louboutin

What is the unit of JUDI's output wavefield and observed time data? I wonder if the u(x,t) in this page

https://wiki.seg.org/wiki/Full-waveform_inversion,_Part_1:_Forward_modeling

denotes displacement field (whose unit is mm when I am using a unit system of mm, g, us), or u(x,t) is the pressure field (whose unit is something like Pa)?

Thanks!

The Wakefield is the pressure as JUDI currently only consider variations of th3 acoustic wave equation.
