Application of modified parameterized schemes

[wbr2023]

Hi, I am a novice to CESM. I am using CESM2.1.3 and several problems were encountered.

I recently read an article by Leung et al. This article is about dust parameterization scheme change and at the end of the article, the article shares The CESM2 code for the new dust emission scheme. I want to apply this scheme to my model setup, may I know exactly how should I use the code provided by him.

Article Citation: Leung, D. M., Kok, J. F., Li, L., Mahowald, N. M., Lawrence, D. M., Tilmes, S., Kluzek, E., Klose, M., and Pérez García-Pando, C.: A new process-based and scale-aware desert dust emission scheme for global climate models – Part II: Evaluation in the Community Earth System Model version 2 (CESM2), Atmos. Chem. Phys., 24, 2287–2318, A new process-based and scale-aware desert dust emission scheme for global climate models – Part II: Evaluation in the Community Earth System Model version 2 (CESM2), 2024.

Sincerely hope to get your advice.
Best wishes!

The Leung option will not be available in the CESM until a newer version that is expected in the next few weeks or months.

Thank you for your reply. Are there any other parameterization schemes that can be used to improve the simulation of sand and dust?

I don't think so. When the Leung method becomes available, that will be an alternative to the current default which is the Zender method.

Thanks for your reply. I am now going to use the default.
