I have compiled WRF-Chem with seven anthropogenic tracers for GHGs and prepared the corresponding tracer files. I have also included all required inputs such as biogenic emissions, anthropogenic emissions, and background concentrations. However, after running WRF-Chem, all tracer fields including biogenic and anthropogenic emissions—are showing zero values, while the physical parameters (such as temperature and pressure) are being simulated correctly.
What could be the reason for this issue?
