The model to evaluate the effects of zonal Earth tides on the Earth's rotation has been updated, with software included, and a model to evaluate tidal variations in polar motion and polar motion excitation due to long period ocean tides has been added (from R. Gross). The subroutine RG_ZONT2 is provided to compute the effects of zonal Earth tides on the rotation of the Earth (from R. Gross).
