There are several tidal analysis software packages available. They differ by the tidal catalog they use, by the way they group the tidal components, by the way they process auxiliary channels, by their method of inversion. Here are the major ones2:

  • ETERNA33 Runs under DOS. Fortran Code source are now available from the Global Geody- namic Project.http://www.eas.slu.edu/GGP/ETERNA/
    Least square inversion. Vast choice of catalogs. Auxiliary channels removed by least-square inversion. Manual selection of tidal wave packets.

  • BAYTAPG Fortran code source available from http://ggpjapan.miz.nao.ac.jp/baytap/uncompress/ Parametric inversion. Tamura or Cartwright catalogs used. Automatic selection of waves packet.

  • PIASD Fortran and C code source available3. Written for UNIX. Code source available by http://igppweb.ucsd.edu/agnew/piasdmain.html.
    Least square inversion. Cartwright catalog. Auxiliary channel have to be preliminary removed (extensive preprocessing abilities are given with the program).
