Guidance on CO2 IC/BC using MOZBC

[Muhammad Burhan Khalid]

Hi All

 My name is Muhammad Burhan, and I am working on CO2 simulations using the WRF-Chem model. I am currently facing an issue with creating the initial (IC) and boundary conditions (BC) using the MOZBC tool.

 My input MOZBC file contains CO2 values ranging from 403 to 500+ ppm, and in my study area the expected value is approximately 412 to 430 ppm. However, after running MOZBC, it populates CO2 background data into the wrfinput and wrfbdy files and the resulting CO2 is much narrower between 404.2 and 404.8 ppm.

Could you kindly guide me on what might be causing this issue?Your help would be highly appreciated.

Best regards,

Muhammad Burhan
