Comparison of Constant Volume Balloons, Model Trajectories and Tracer Transport during ETEX.
The paper validates trajectories calculated from ECMWF analyses against the tracks of constant volume balloons(CVBs) released during the European Tracer Experiment (ETEX). The agreement between the calculated trajectories and the balloon tracks was very good for the first experiment and excellent for the second one. This is in sharp contrast to the results of the dispersion models which all failed in the prediction of the perfluorocarbon tracer dispersion for the second experiment. A likely explanation for this is that vertical motions, possibly on small scales, were not correctly captured by the ECMWF analyses, but it is not possible to clarify this with the CVB data.
