Modified TMD Matlab Toolbox

This is a modification of the Matlab Tide Model Driver (TMD):

https://www.esr.org/research/polar-tide-models/tmd-software/

Originaly developed by Laurie Padman

This wraper runs tmd_tide_pred.m in parallel on several HDF5 files.

Notes

Some original Matlab scripts have been modified to improve performance.

Modifications include replacing loops by vectorization, and improving the I/O to allow multiple input data files and parallelization.

Modifications were made by Alex Gardner and Fernando Paolo, and they have been marked in the code.

Usage

The main script to run is (see header for documentation):

tmd_toolbox/tidecor.m 

For optimal performance, merge/split the input files into N blocks, whith N equal number of cores (even if the files end up fairly large). To merge/split use (from captoolkit):

merge.py 
split.py

For downloading the lasted Tide Model and TMD Matlab toolbox:

(TMD)   http://www.esr.org/ptm_index.html  
(Model) https://www.esr.org/polar_tide_models/Model_TPXO71.html

Recipe

Clone the package:

git https://github.com/fspaolo/tmdtoolbox.git

Add models:

cd tmdtoolbox
mkdir DATA
# put Model_* and grid_* files into DATA

Edit the header of tidecor.m, and run:

/Applications/Matlab2016b/bin/matlab -nodesktop < tidecor.m

Notes

The tide and load-tide corrections are applied as:

h_cor = h - tide - load

or equivalentely, the full tide correction is:

h_tide = tide + load
