Modeling of dispersion of air pollutants in the atmosphere is one of the most important and
challenging scientific problems. There are several natural and anthropogenic events where …

The city of London, UK, has seen in recent years an increase in the number of high-rise/multi-
storey buildings (“skyscrapers”) with roof heights reaching 150 m and more, with the Shard …

Multi-pollutant chemical transport models (CTMs) are being routinely used to predict the
impacts of emission controls on the concentrations and deposition of primary and secondary …

A new physical analogy for the discrete approximation of the vertical diffusion equation is
presented. It is based on the resistor‐capacitor chain and incorporates the classical …

Atmospheric pollutant plumes are not well resolved in current air quality models due to
limitations in grid resolution. Examples of these include power plant and biomass burning …

Application of an Eulerian model using layered adaptive unstructured grids coupled to a
meso-scale meteorological model is presented for modelling the dispersion of nuclear …

An unstructured mesh finite volume discretisation method for simulating diffusion in
anisotropic media in two-dimensional space is discussed. This technique is considered as …

The predictions from air quality models are subject to many sources of uncertainty; among
them, grid resolution has been viewed as one that is limited by the availability of …

We discuss an adaptive resolution system for modeling regional air pollution based on the
chemical transport model STEM. The grid adaptivity is implemented using the generic …

This paper develops a mobile sensing system, the first system used in adaptive resolution
urban air quality monitoring. In this system, we employ several taxis as sensor carries to …
