- Аннотация: The nutation series ZP2002 based on geophysical theory of the non-rigid Earth with the atmosphere was obtained. The modeling of precession and nutations is based on a fit to the VLBI observational data. A brief description of the series is presented. The series ZP2002 was obtained by convolution of the rigid Earth nutation series with the transfer function. The resonance parameters and frequencies of the transfer function are determined by the Earth structure. They were calculated by taking into account physical limitations related to the Earth's inner structure parameters. Another important step is an incorporation of additional effects in order to create a more accurate theory. In particular, we investigate the role of the atmosphere as well as viscosity of the liquid core on nutation. The wrms errors of residuals in deps is 0.29 mas, and in sin(eps0)dpsi is 0.20 mas (the FCN model is not included in ZP2002 series).
