The representation of soil moisture in Earth System Models, like the Community Earth System Model (CESM), is an essential facet in modeling the response of the Earth System to climate change. Since their inception, land models have grown to represent critical processes like carbon cycling, ecosystem dynamics, terrestrial hydrology, and agriculture. They serve as a lower boundary condition for atmospheric general circulation models. With increasing process representation, they are computationally expensive. Hydrologists and modelers use several parameterization schemes to describe the water and energy balance. However, this is regarded as computationally expensive. Alternative tools called emulators (e.g., machine learning and artificial intelligence) incorporated with the empirical orthogonal function analysis can represent soil moisture.
