PROFILE
Yunpeng Shan
During February 2025, Yshan focused on improving the EAM model within the E3SM repository by addressing a critical configuration issue affecting atmospheric dust emissions. Yshan identified and corrected the default dust emission cap, updating it from 1e-5 to 1e-4 kg/m2/s to ensure simulation fidelity. This work involved coordinated changes across both the user_nl_eam test definitions and the aero_model.F90 source file, requiring careful validation to maintain alignment between configuration and code. Utilizing Fortran, configuration management, and domain expertise in atmospheric chemistry, Yshan’s targeted bug fix enhanced the reliability of climate modeling outputs by preventing misconfigured dust emission limits.

Feb 1, 2025February 2025 monthly summary for the E3SM project (repository: E3SM). Key accomplishments center on a critical bug fix in the EAM model: corrected the default dust emission cap from 1e-5 to 1e-4 kg/m2/s, with changes propagated to the user_nl_eam test and aero_model.F90 to enforce the intended default. This fix ensures simulations use the correct default cap, improving model fidelity and reducing risk of misconfigured dust limits affecting results. Top achievements include updating test definitions to reflect the new default and validating configuration-code alignment across files. Technologies and skills demonstrated include debugging across configuration and code, Git version control, cross-file edits, and domain knowledge of atmospheric dust emissions.
