Toward Routing River Water in Land Surface Models with Recurrent Neural Networks

1 code implementation22 Apr 2024 Mauricio Lima, Katherine Deck, Oliver R. A. Dunbar, Tapio Schneider

Training of such a model over the continental United States has demonstrated that a single set of model parameters can be used across independent catchments, and that RNNs can outperform physics-based models.

Learning About Structural Errors in Models of Complex Dynamical Systems

1 code implementation29 Dec 2023 Jin-Long Wu, Matthew E. Levine, Tapio Schneider, Andrew Stuart

Complex dynamical systems are notoriously difficult to model because some degrees of freedom (e. g., small scales) may be computationally unresolvable or are incompletely understood, yet they are dynamically important.

Tipping Point Forecasting in Non-Stationary Dynamics on Function Spaces

no code implementations17 Aug 2023 Miguel Liu-Schiaffini, Clare E. Singer, Nikola Kovachki, Tapio Schneider, Kamyar Azizzadenesheli, Anima Anandkumar

Tipping points are abrupt, drastic, and often irreversible changes in the evolution of non-stationary and chaotic dynamical systems.

Iterated Kalman Methodology For Inverse Problems

1 code implementation2 Feb 2021 Daniel Z. Huang, Tapio Schneider, Andrew M. Stuart

In this paper, we work with the ExKI, EKI, and a variant on EKI which we term unscented Kalman inversion (UKI).

Calibration and Uncertainty Quantification of Convective Parameters in an Idealized GCM

no code implementations24 Dec 2020 Oliver R. A. Dunbar, Alfredo Garbuno-Inigo, Tapio Schneider, Andrew M. Stuart

Here we demonstrate an approach to model calibration and uncertainty quantification that requires only $O(10^2)$ model runs and can accommodate internal climate variability.

Earth System Modeling 2.0: A Blueprint for Models That Learn From Observations and Targeted High-Resolution Simulations

no code implementations31 Aug 2017 Tapio Schneider, Shiwei Lan, Andrew Stuart, João Teixeira

Climate projections continue to be marred by large uncertainties, which originate in processes that need to be parameterized, such as clouds, convection, and ecosystems.
