GCHP 13.2.1 Simulation Issue — Abnormal Ozone Output #451

Please provide a clear and concise description of your question or discussion topic.

I am reaching out to seek your advice regarding an issue I encountered while running a simulation using GCHP version 13.2.1.

Specifically, I am trying to obtain simulated ozone results for the year 2015. The simulation is set up with the default restart file for July 2019, using the MEIC inventory for China, at a resolution of C90 with a stretch factor of 2. I initiated the run in July 2014, intending to use the period from July to December 2014 as spin-up time.

However, I am facing a puzzling problem: the spatial distribution and values for January to April 2015 appear to be completely incorrect, while the results for July to December 2014 and June to December 2015 seem reasonable. I have attached the monthly MDA8 O3 data I obtained from the raw results for your reference.

This issue doesn't appear to stem from the MEIC inventory, as the results for other months are plausible. Therefore, I am quite confused by this anomaly and was wondering if you have encountered a similar problem or if you might have any suggestions on how to resolve this.

I would greatly appreciate your insights!

Thanks for writing @mmmjjj527. GCHP 13.2.1 is no longer supported, as there have been many bug fixes and improvements since then. We would recommend updating to the most recent version.
