The RADS implementation of the Cartwright-Taylor-Edden solid earth tide model includes 386 second order waves and 99 third order waves \citep{cartwright1971,cartwright1973}.

The pole tide is the vertical deformation of the earth crust as a result of polar motion. We can visualise this as the ellipsoidal shape of the earth being moved as the rotation axis of the earth moves away or closer to the mean pole \citep{munk1960}. We use the IERS(EOP)05C04 earth orientation parameters and their predictions. The motion of the mean pole, describing the effect of global isostatic adjustment (GIA) is represented by a linear motion, as suggested by \citet{wahr2015} following the work of \citet{argus2012}. The implicit effect on pole tide is further discussed by Desai (forthcoming work, private communication).

Two Love numbers multiply the results of this simple equilibrium model: $(1 + k_2)$ = 1.302 for the combination of solid earth and oceans, and $h_2$ = 0.609 for the solid earth only (over land and lakes) \citep{wahr1985}.
