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
