Abstract. A method for calculating the tilts of the earth's surface due to atmospheric loading effect is presented. The loading tilts, taking into account the effect of direct Newtonian attraction, are calculated by the expansion coefficients for the spherical functions of the surface atmospheric pressure fields of the European reanalysis project ERA5, as well as the load Love numbers that we calculated earlier. A comparison of the obtained time series of tilts (in the direction of north and east) with the works of other authors was carried out.

Keywords: atmospheric loading effect, tilts of the earth's surface, load Love numbers, European ERA5 reanalysis project
