Ocean Tide Model GUI in MATLABI have a nifty MATLAB GUI package for Gary Egbert's global TPXO tidal models. This package allows one to plot tidal ellipses at particular points, extract harmonic constants for those points, and then make a past or future tide prediction for that point. People have also used the figures produced by this package for talks, etc. A separate package can be set up to get line-averaged tide predictions that might be used for acoustic tomography. The package includes high-resolution coastlines for the world in matlab format. In the interest of conserving disk space, I've extracted the model output for specific areas: Hawaii (high-resolution 1/30 deg), the North Pacific, the western North Atlantic, the West Coast of North America (higher-resolution 1/12 deg), and for a large section of the Southern Ocean (India, Australia, New Zealand). More information on the TPXO model may be found at the OSU Tidal Data Inversion web site. You can see a screen shot of the package in action by clicking HERE. (125 KB) These downloads are all in the form of gzipped tar balls (".tgz" extension). You will need to gunzip them, and then untar them. Or merely "tar xfz filename.tgz". Extract the packages into their own directory. You will probably need some familiarity with MATLAB. For any of these packages, first download the world shoreline data. (6.7 MB compressed, 16 MB uncompressed) Then, get one or more of the following packages: 1/30 degree resolution Hawaiian Island package.
(23 MB compressed, 87 MB uncompressed) 1 degree resolution North Pacific package. (TPXO.5) (8.2 MB compressed, 36 MB uncompressed) 1 degree resolution Western North Atlantic package. (TPXO.5) (1.6 MB compressed, 5.6 MB uncompressed) 1/2 degree resolution South Atlantic package (15N-85S). (TPXO.5) (4.4 MB compressed, 17.6 MB uncompressed) 1 degree resolution Southern Ocean package (mainly Pacific). (TPXO.5) (8.3 MB compressed, 27 MB uncompressed) 1/12 degree resolution U.S. West Coast package. (2.4 MB compressed, 11 MB uncompressed) If you'd like to make predictions for line averages, get the Line Averaging Package (77 KB compressed, 312 KB uncompressed), together with a package above for a region of interest. You can read a README file for using this package. |
