Hello everyone, I have a question I'd like to ask. I am currently running the CLM model to simulate regional methane fluxes. However, the atmospheric methane concentration is currently set as a fixed parameter. I would like to input dynamic atmospheric methane concentrations, similar to how CO₂ and nitrogen deposition are handled. So, I created a stream file for methane, following the same approach as CO₂. In all the source code sections that involve CO₂, I added similar settings for methane. In the generated log file, I can see that the methane file was successfully opened. However, when I printed out the methane concentration after reading it, the output value was zero. I realized that the methane data might not have actually been read. I'm not sure where the issue lies. I have tried multiple times to locate the error but haven't been able to find it. I would really like to understand why this is happening. If anyone could share the relevant settings for CO₂ or nitrogen deposition, I would greatly appreciate ！
