Model Validation Kit - recent developments
Over the past few years, the so-called Model Validation Kit has been the basis for much work on model evaluation. The ground is presently being prepared for further development of the kit. Based on data from the Kincaid experiment investigations have been carried out in order to illuminate features and problems with a methodology for model evaluation proposed in the context of the ASTM. Certain problems with the determination and use of near-centreline concentrations (NCCs) are identified and discussed. A study of crosswind-integrated concentrations from the Kincaid experiment has been conducted; as a by-product, the study has revealed data problems with a certain version of the Kincaid dataset.
