Hello, professor, I would like to ask you a question. At present, I process the file after DDM, which is CCTM\_SENDDEP\_v54\_intel\_d01\_20170202.nc, and the processing result is shown in the file. I find that it only shows the level level is 0 and the contribution of NMVOC to FORM for each grid. Does it not distinguish the effect of emission from grid 1 on grid 2, only the effect of emission from grid 1 on grid 1 can be shown?
