Note that the precision is very good, however the accuracy is nowhere near as close (fractions of a metre) in the atmosphere, due to the variable refractive index of air. Long term averages can help, of course.

They talk about this technique for ranging between satellites, which wouldn't have to deal with atmospheric conditions.
For ranging in an atmosphere they suggest dual-comb spectroscopy or two-color methods to account for the atmospheric changes.
