Now my understanding is that unit conversion between t(:,:,:.nnew.itrc) and t(:,:,:,nstp,itrc) is done only in step3d_t.F, while in ohter subroutines like sediment and biology, the unit of t(:,:,:,nnew,itrc) is always m*Tunit, Am...

Hi all, Since I do not fully understand the tracer algorithm in ROMS, I have some question about the tracer routine.
