Compression of Climate Simulations with a Nonstationary Global Spatio-Temporal SPDE Model
Fuglstad, Geir-Arne; Castruccio, Stefano (Peer reviewed; Journal article, 2020)Modern climate models pose an ever-increasing storage burden to computational facilities, and the upcoming generation of global simulations from the next Intergovernmental Panel on Climate Change will require a substantial ... -
High Resolution Global Precipitation Downscaling with Latent Gaussian Models and Nonstationary SPDE Structure
Zhang, Jiachen; Bonas, Matthew; Bolster, Diogo; Fuglstad, Geir-Arne; Castruccio, Stefano (Journal article, 2023)Obtaining high-resolution maps of precipitation data can provide key insights to stakeholders to assess a sustainable access to water resources at urban scale. Mapping a non-stationary, sparse process such as precipitation ... -
A Stochastic Locally Diffusive Model with Neural Network-Based Deformations for Global Sea Surface Temperature
Hu, Wenjing; Fuglstad, Geir-Arne; Castruccio, Stefano (Peer reviewed; Journal article, 2021)In this work, we propose a new approach to model large, irregularly distributed spatio-temporal global data via a locally diffusive stochastic partial differential equation (SPDE). The proposed model assumes a local ...
