On the modeling of atmospheric pollutant dispersion during a diurnal cycle: A finite element study
TL;DR: In this paper, the authors presented a numerical model to study pollutant dispersion in the atmospheric boundary layer (ABL) by accounting for the mechanisms of advection by the mean wind in the horizontal direction, turbulent diffusion in the vertical direction to ground surface, dry deposition, and radioactive decay.

Isogeometric Residual Minimization Method (iGRM) with direction splitting for non-stationary advection–diffusion problems
TL;DR: The method mixes the benefits resulting from isogeometric analysis, implicit dynamics, residual minimization, and alternating direction solver with direction splitting, and shows that the resulting system of linear equations has a Kronecker product structure, which results in a linear computational cost of the direct solver.

A multimesh adaptive scheme for air quality modeling with the finite element method
TL;DR: In this paper, a multimesh adaptive scheme for convection-diffusion-reaction problems for a large number of components is presented, where the evaluation of the nonreactive part for each component and the reaction at each node constitute independent tasks.

TL;DR: This work compares a variety of integration techniques, including methods proposed by Hesstvedt et al. and finds that Gear-type solvers such as the Livermore Solver for ordinary differential equations (LSODE) and the sparse-matrix version of LSODE (LSODES) provide the most accurate solution of the test problems with the least computational effort.
