چکیده
In air pollution models, semi-Lagrangian methods are often used to solve the ad-vective part of the corresponding model equation. Interpolation is an essential part of these methods. In this note, ve diierent interpolation methods will be discussed and results of numerical experiments will be presented. To keep the concentration eld nonnegative, ltering techniques are used. Also a monotone interpolation method is examined.

Mesh-free Semi-Lagrangian Methods for Transport on a Sphere Using Radial Basis Functions
We present three new semi-Lagrangian methods based on radial basis function (RBF) interpolation for numerically simulating transport on a sphere. The methods are mesh-free and are formulated entirely in Cartesian coordinates, thus avoiding any irregular clustering of nodes at artificial boundaries on the sphere and naturally bypassing any apparent artificial singularities associated with surfac...
متن کاملA Semi-largangian Method on Dynamically Adapted Octree Meshes
The paper develops a semi-Lagrangian method for the numerical integration of the transport equation discretized on adaptive Cartesian cubic meshes. We use dynamically adaptive graded Cartesian grids. They allows for a fast grid reconstruction in the course of numerical integration. The suggested semi-Lagrangian method uses a higher order interpolation with a limiting strategy and a back-and-for...

We describe the remapped particle-mesh method, a new mass-conserving method for solving the density equation which is suitable for combining with semi-Lagrangian methods for compressible flow applied to numerical weather prediction. In addition to the conservation property, the remapped particle-mesh method is computationally efficient and at least as accurate as current semi-Lagrangian methods...
متن کاملA semi-Lagrangian AMR scheme for 2D transport problems in conservation form
In this paper, we construct a semi-Lagrangian (SL) Adaptive-Mesh-Refinement (AMR) solver for 1D and 2D transport problems in conservation form. First, we describe the à-la-Harten AMR framework: the adaptation process selects a hierarchical set of grids with different resolutions depending on the features of the integrand function, using as criteria the point value prediction via interpolation f...
متن کاملA semi-Lagrangian scheme with radial basis approximation for surface reconstruction
We propose a Semi-Lagrangian scheme coupled with Radial Basis Function interpolation for approximating a curvature-related level set model, which has been proposed by Zhao et al. in [19] to reconstruct unknown surfaces from sparse, possibly noisy data sets. The main advantages of the proposed scheme are the possibility to solve the level set method on unstructured grids, as well as to concentra...
