Abstract
Attempts to use ETEX-I data to reconstruct the source term of the experiment has been shown to be rather successful by means of variational data assimilation using the Eulerian transport model MATCH (Robertson and Langner, 1998). We have taken one step further and investigated the possibilities of quality control of data within the concept of variational data assimilation. With the adopted strategy it is found that the quality control mainly skip zero observed values, that does not agree with the model. To some extent is this justified by the representative error in the measurements in relation to the scale over which the model is valid. So far we have not gained anything but experience from this quality control approach. The quality control does not improve the model performance which never the less encourage us to further investigate the use of quality control.
