Assessing Emulator Design and Training for Modal Aerosol Microphysics Parameterizations in E3SMv2
Researchers have explored the use of Scientific Machine Learning (SciML) emulators to enhance the representation of aerosol processes in global atmospheric models. Their study focused on emulating aerosol microphysics within the Energy Exascale Earth System Model version 2 (E3SMv2), examining factors like network architecture complexity and variable normalization. The findings indicate that optimization convergence, scaling strategies, and network complexity significantly impact emulation accuracy, with simpler architectures achieving promising results when properly scaled and converged.
