Abstract:

The program RIGTID together with its subroutines computes the tidal accelerations on a rigid earth, i. e. no response of the Earth is considered. The tidal accelerations are calculated directly from the positions of moon and sun separately, i. e. if wanted two groups of tides (solar or lunar) can be handled differently. The program does not use a potential development, it includes the second, third, and fourth degree potential of the moon, but only the second degree potential of the sun. It treats the earth as an elliptically shaped body but does not include the direct effect of the earth's ellipticity on the tidal accelerations (Wilhelm 1983 and Dahlen 1993). It also does not take into account the speed of light. No planets are included, this is discussed by Broucke, Zuern, and Slichter, (1972, DOI: 10.1029/GM016p0319). This program was developed at UCLA in 1971/72 by Walter Zuern with the help of subroutines provided by Roger Broucke from JPL describing the position of the moon much more accurately than is done by the program developed by Longman previously. The description of the celestial mechanics of the Earth-Moon-Sun system was still very accurate in 2017 when compared to ephemerides, which are the basis of the most modern tidal potential catalogues. ... mehr
