Dear all:
I would like to ask for your advice. When simulating CO2 concentrations using WRF-Chem version 4.0 coupled with VPRM, with exactly the same anthropogenic emissions inventory, VPRM input files, and namelist.input, the spatial distribution of CO2 concentration results appears normal when I run only D01. However, when employing a three-layer nesting, with each layer using its respective emissions inventory and VPRM input files, the spatial distribution of the D01 results becomes very odd. Within the grids covering the D02 area in the D01 results, the concentrations of CO2_ANT and CO2_BIO are extremely low, almost as if there were no emissions in the D02 area. However, checking the rsl.out files shows that the D02 anthropogenic emissions data and VPRM input data are being read correctly, and the emissions data for all three nested layers also appear normal with VERDI. What could be causing this issue? In the image attached, the area enclosed by the red rectangle is my D02 range, and the concentrations seem to be significantly lower than in other areas. I welcome any suggestions and thank you very much.Attached file is the namelist.input and part of my rsl.out.0000 file and the wrfout file plot CO2_ANT with VERDI.
