Few east European countries established the geophysical program in 1966 named KAPG (complex planetary geophysical research), part of which dealt with the atmospheric physics and meteorology.
For the KAPG project III-1 "Physics of interaction processes of the non-steady-state ABL with a non-homogeneous underlying surface" the two scale VAT urban air pollution and meteorology models were developed in the late 80-th with the mutual intention to apply them for one of the GDR large city air pollution study case
