The paper concerns on the conception of a determination of reduced gravity anomalies Ag* after Bjerhammar using the vertical gravity gradient (delta)G determined directly by observations in terrain. The results of gravity anomaly reduction are presented for global model data and for the real gravity field charavteristics near Grybow. The two experiments results pointed out that introducing the (delta)G anomalies demands more detailed process of free-air gravity reduction and introduction of the gravity topographic reduction before Ag* determination.
