Description
A factor of dt(ngc)/dt(ngf) was missing in the computation of the vertically integrated tracer flux correction (TFF) in two-way nesting in private routine correct_tracer_tile of nesting.F:
TFF=TFF*dt(ngc)/dt(ngf)
The correction is small but it may make a difference in some applications at the refined grid boundary. It assumes that the coarse grid tracer flux remains constant over all fine grid mini-time steps.
Many thanks to Richard Leighton for his excellent description and solution to this problem. Check his application before and after the fix.
