Help with message in rsl files related to photolysis driver

[jhernadi]

Hi all.

I am running several exercises with the WRF-Chem v4.1.1, verifying the execution log (rsl files), I have observed a recurring message, which is presented just before the "photolysis_driver: called for domain". The message is:

The emission files are hypothetical and I have generated them manually. The configuration I am using is:

How should I interpret this message? Is it an instability of the model? In case of a numerical instability, how could it be solved?

Thank you very much for reading the message and the help provided.

I ran into this same error last week. For me, I believe the solution was to stop using the preset physics suites ('tropical' in the namelist below). I simply manually input the namelist parameters for the given physics suite instead and the repeated messages went away.

Hopefully this helps someone in the future!
