Hello, I'm interested in running WRF with tracers to simulate the dispersion of CO₂, but without including any chemical processes. Is it possible to do this without using WRF-Chem? Any guidance would be greatly appreciated.

WRF with tracers to simulate the dispersion of CO₂
- Thread starter llsalazardom
- Start date
WRF has the option of tracer_opt, which activates a few pre-defined tracers. I suppose this option may be helpful for your CO2 dispersion study.
Please take a look at the WRF User's Guide for its application (Chapter 5: WRF Model).

Hi, thank you for your help.
I’d like to ask: how can I find out which tracers are predefined? I want to understand what each tracer represents.

Please take a look at the file "WRF/Registry/Registry.EM", in which you can find the following piece of code:
These are predefined tracers.
Code:
# Tracer Scalars: If you want full resolved and non-resolved dispersion, compile WRF-Chem
