Budget Equation: u c + K Dc/Dx + q = Dc/Dt
„Classical“ Inverse - Drawback
The „classical“ inverse
approach requires observations on all boundaries of a
given control volume. For
transient tracers, the time-rate of change also has to
be known (repeat
measurements required).
Usually, these requirements
can not be met (e.g., transient tracers CFC, aCO2,
etc.; arbitrary,
model-dependent grid-volumes/boxes).
