Quantifying Urban Morphology‐Induced Uncertainty in Urban Meteorology and Heat Stress Simulations in Southern California

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Accurate representation of land use and urban morphological parameters (UMPs), particularly building height, road width, and roof width, is critical for urban climate/weather modeling. The Weather Research and Forecasting (WRF) coupled with the Single‐Layer Urban Canopy Model (SLUCM) has been widely used; however, few studies have quantified ...

Sparse polynomial chaos expansion for universal stochastic kriging

open access: yesJournal of Computational and Applied Mathematics
Surrogate modelling techniques have opened up new possibilities to overcome the limitations of computationally intensive numerical models in various areas of engineering and science. However, while fundamental in many engineering applications and decision-making, the incorporation of uncertainty quantification into meta-models remains a challenging ...

Uncertainty Quantification at the Molecular–Continuum Model Interface †

open access: yesFluids, 2017
Non-equilibrium molecular dynamics simulations are widely employed to study transport fluid properties. Observables measured at the atomistic level can serve as inputs for continuum calculations, allowing for improved analysis of phenomena involving ...

Combining Polynomial Chaos Expansions and Kriging

open access: yes, 2014
Computer simulation has emerged as a key tool for designing and assessing engineeringsystems in the last two decades. Uncertainty quantification has becomepopular more recently as a way to model all the uncertainties affecting the systemand their impact onto its performance.In this respect meta-models (a.k.a.
