N2 - It is shown that the kinematic analysis of the UCAC4, PPMXL and XPM proper motions in northern and southern Galactic hemispheres detects retardation of the Galaxy’s rotational velocity and acceleration of the expansion velocity of the stellar system with increasing the distance from the principal Galactic plane. The estimates of the vertical gradient of the Galactic rotation are UCAC4: 40:1 § 0:2; PPMXL: 36:2 § 0:4; XPM: 37:7 § 0:1 km ¢ s¡1 ¢ kpc¡1, while the values of the vertical gradient of the expansion velocity turned out to be UCAC4: 11:9 § 0:2; PPMXL: 19:0 § 1:1; XPM: 10:9 § 0:3 km ¢ s¡1 ¢ kpc¡1.
