DALES v4.2 modified for ammonia plume dispersion and blending-distance estimations



A modified version of the DALES model version 4.2 for the purpose of studying ammonia plume dispersion in a polluted atmosphere. With the data in this repository, the fine-scale simulation framework can be applied to individual locations to study the representativity of (potential new) measurement sites under the local conditions, using the concept of blending-distance. This repository contains the modified DALES code, instruction, MATLAB processing scripts and example input files of the reference experiment are added to the repository. The modifications with respect to DALES v4.2 are described in the publication.
