Uncertainty Quantification for Reduced-Order Surrogate Models Applied to Cloud Microphysics
Jonas E. Katona, Emily K. de Jong, Nipun Gunawardena
Reduced-order models (ROMs) can efficiently simulate high-dimensional physical systems but lack robust uncertainty quantification methods. Existing approaches are frequently archit…
