All concentration files are correct, and the logs have not reported any errors. However, one day after the simulation started, mine was on the 10th day, O3_ ANX starts from a certain grid point in the simulation domain to 0. As the simulation continued, after another 7 days, O3_ BCO also began to become zero. There are also issues with other variables. Given that there were no issues with the results at first few days of the simulation, I guess my model settings should not have been wrong.
I have not been able to replicate this behavior on our local system here. Is there any way for you to share the INPUTS so that I may try your exact case? The best would be the smallest number of simulation days that start from clean initial conditions and progress in the the first occurrence of the problem.
@sergey, no, unfortunately I think @bandaoshutiao is encountering the problem with the newest code (CMAQv5.4.0.3), but can avoid this specific problem when downgrading to CMAQv5.3.2.
I have successfully executed CMAQ/DDM v5.2 and CMAQ/DDM v5.4.0.3 and obtained satisfactory results. In my practices, other versions of CMAQ, including CMAQ 5.3.2 with the DDM-3D, do not appear to be fully functional.
CMAQ/DDM v5.4 exhibits significantly elevated higher-order sensitivities. However, these issues have been addressed and resolved in CMAQ v5.4.0.3, as seen here. I do not have the problem posted here in utilizing CMAQ v5.4.0.3 with DDM-3D.
Thanks.
