Stabilized Explicit Time Integration for Parallel Air Quality Models
Air Quality Models are defined for prediction and simulation of air pollutant concentrations over a certain period of time. The predictions can be used in setting limits for the emission levels of industrial facilities. The input data for the air quality models are very large and encompass various …

Improving a priori emission estimates using network observations and a perturbed emissions ensemble: a study in Beijing
Emissions inventories are essential inputs in air quality modelling from global to local scales, but they also represent a major source of uncertainty in the simulation outputs. Uncertainties may be propagated from the underlying data used to compile the emissions inventories or they can arise from …
