The Maximum Cross Correlation method (MCC) modified with divergence checking was used to calculate the surface velocity field in the Gulf of Gdansk. The brightness temperature in channel 4 of the AVHRR taken 10 times between 6 and 9 August 1996 served as input data. The surface velocity vector distribution obtained with the use of MCC are compared with the results of a 3D hydrodynamic model and field observation of a drifting rhodamine spill during the POLRODEX?96 experiment.
