GASTAR has participated in major validation exercises, such as those of Hanna et al.1 and SMEDIS2. The comparative exercise of Hanna et al. showed GASTAR to be one of the best performers for the standard data sets in flat terrain; while in SMEDIS the model was able to simulate successfully data sets from a wide range of experiments, most featuring one or more of the complex effects of slopes, obstacles and aerosols.
