Abstract: The so-called Model Validation Kit has been used as a basis for modelling exercises at workshops in Manno (1993), Mol (1994) and at the present workshop. It is a practical tool, meant to serve as a common frame of reference for modellers. It consists of three experimental datasets, accompanied by software for model evaluation. Before the present workshop, a pilot study was conducted, aimed at extending the original toolkit with datasets from two additional experimental campaigns. These |new| datasets contain data from experimental campaigns at Indianapolis (urban) and Bull Run (moderately complex terrain). Both campaigns deal with emissions from a single stack, and include detailed tracer measurements from several hundred hours. The present paper gives an introduction to the two |new| datasets. A large part of the paper, however, is used to convey general experiences on the preparation and use of performance-evaluation datasets. The context of this work is discussed; particular emphasis is on its relation to a planned catalogue of models, which will become available through the World Wide Web.
