In Part I (Schwiderski, 1978a) of this report, a unique hydrodynamical interpolation technique was introduced, extensively tested, and evaluated in order to compute partial global ocean tides in great detail and with a high degree of accuracy. This novel method has been applied to construct the semidiurnal elliptical lunar (N2) ocean tide with a relative accuracy of better than 5 cm anywhere in the open oceans. The resulting tidal amplitudes and phases are tabulated on a 1 deg x 1 deg grid system in an atlas of 42 deg x 71 deg overlapping charts covering the whole oceanic globe. A corresponding atlas of global corange and cotidal maps is included to provide the reader with a quick general overview of the major tidal phenomena. The specifying hydrodynamical parameters of the model are listed along with quoted sources of empirical tide dta, and significant tidal features are explained and discussed. The semidiurnal N2 ocean tide is found to resemble closely the semidiurnal M2 and S2 tides (compare Parts II and III). As mentioned in Parts II, III, IV, and V only qualitative similarities are displayed between the semidiurnal and diurnal ocean tides. (Author).

In Part I (Schwiderski, 1978a) of this report, a unique hydrodynamical interpolation technique was introduced, extensively tested, and evaluated in order to compute partial global ocean tides in great detail and with a high degree of accuracy. This novel method has been applied to construct the diurnal elliptical lunar (Q1) ocean tide with a relative accuracy of better than 5 cm anywhere in the open oceans. The resulting tidal amplitudes and phases are tabulated on a 1 x 1 deg grid system in an atlas of 42 x 71 deg overlapping charts covering the whole oceanic globe. A corresponding atlas of global corange and cotidal maps is included to provide the reader with a quick general overview of the major tidal phenomena. The specifying hydrodynamical parameters of the model are listed along with quoted sources of empirical tide data, and significant tidal features are explained and discussed. The diurnal Q1 tide resembles all other computed diurnal tides K1, O1, and P1 (see Part IV, V, and VII). Qualitative similarities exist also between the diurnal and semidiurnal species M2, S2, N2, and K2 (see Parts II, III, VI, and VIII). (Author).

In Part I (Schwiderski, 1978a) of this paper, a unique hydrodynamical interpolation technique was introduced, extensively tested, and evaluated in order to compute partial global ocean tides in great detail and with a high degree of accuracy. This novel method has been applied to construct the leading semidiurnal principal lunar (M2) ocean tide with an accuracy of better than 5 cm anywhere in the open oceans. The resulting amplitudes and phases are tabulated on a 1 degree x 1 degree grid system in an atlas of 41 degrees x 71 degrees overlapping charts covering the whole oceanic globe. A corresponding atlas of global corange and cotidal maps is included to provide the reader with a quick general overview of the major tidal phenomena. The specifying hydrodynamical parameters of the model are listed along with quoted sources of empirical tide data, and significant tidal features are explained and discussed. (Author).
