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.

Models for information propagation on graphs

no code implementations19 Jan 2022 Oliver R. A. Dunbar, Charles M. Elliott, Lisa Maria Kreusser

We propose and unify classes of different models for information propagation over graphs.

Ensemble Inference Methods for Models With Noisy and Expensive Likelihoods

no code implementations7 Apr 2021 Oliver R. A. Dunbar, Andrew B. Duncan, Andrew M. Stuart, Marie-Therese Wolfram

The ensemble Kalman methods are shown to behave favourably in the presence of noise in the parameter-to-data map, whereas Langevin methods are adversely affected.

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.
