To extract tidal harmonic constants and/or predict tide using a regional tidal solution you MUST first download OTPS (OSU Tidal Prediction Software) or OPTPSnc (same as OTPS, but for our models in netcdf format). OTPS(nc) is written in Fortran 90 and tested under UNIX/Linux. The compressed and tarred OTPS(nc) packages contain README files with details on tidal solution installation and usage. There also exist a MATLAB toolbox, created in cooperation with  Laurie Padman (ESR), called Tidal Model Driver (TMD), functionally the same as OTPS. The TMD toolbox also includes a friendly graphical user interface. Use menu on the left to download TMD and/or Antarctic Tidal Models.
