China Seas & Indonesia 2016
CSI representers and data
Bathymetry: GEBCO   Resolution: 1/30º;
1801x2161 grid;
OBC: TPXO8
Constituents: m2, s2, n2, k2, k1, o1, p1, q1
Data assimilated: Topex Poseidon 531 cycles and Topex Tandem+Jason 225 cycles (all available data),
ERS/Envisat 249 cycles (in shallow water), total 156779 data sites, 915 representers (red filled circles).
Data for validation (not assimilated & not shown): 51 coastal tide gauges taken from [Zu, Gan, Erofeeva 2008]; 44  "truth shallow" (TSW) and 9  "truth coastal" (TC) tide gauges from the sets compiled by Richard Ray as described in Stammer et al.. The model is part of TPXO8-atlas, v1.

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.
