Identification of initial data in the three-dimensional model of passive impurity transport in the Black Sea
The Model of the passive impurity transport based on TVD-schemes is considered. The initial field is identified using the variation algorithm of measurement data assimilation. Test calculations of initialization of the oceanographic fields of various natures are done based on the model of passive impurity transport of the Black Sea. Assimilation of actual data of 137Cs measurements in the transport model is carried out. The initial special isotope distributions in the water areas under study are reconstructed.
