Summary

The so-called Model Validation Kit is a compilation of field data sets, software and documentation that provides a framework for evaluation of atmospheric dispersion models.

The kit has been used extensively by a large number of research groups since it was first introduced in 1993. In particular, it has been used for a series of workshops and conferences on Harmonisation within Atmospheric Dispersion Modelling for Regulatory purposes (see www.harmo.org).

The present report is a User's Guide to the kit, and provides an overview of the entire material. Besides data sets and software for model evaluation, the package also includes supplementary material, such as a data visualisation tool and video film from experiments.

In autumn 2005 the Model Validation Kit has undergone a major revision, resulting in version 2.0. The new version allows the same studies to be carried out as the previous version, but it has been revised in several respects. New software and computing environments have made it necessary to update the package. Furthermore, the documentation is significantly improved and brought up to date. The package can be downloaded from the Internet at www.harmo.org/kit
