The study is an attempt to estimate accuracy of two global geopotential models EGM96 and EGM08. Accuracy of the models was estimated with reference to Lower Silesia area. It analyse values of gravity disturbances and height anomalies. For comparisons there were used 92546 gravity points and 29 points of the POLREF network. Carried analyses have confirmed superior accuracy of the EGM08 model. Standard deviations of residual height anomalies, has an amount ± 16 cm for EGM96 and ± 2.8 EGM08 model.
