Fes2004
From MohidWiki
Fes2004 is the tide level and harmonic predictor for tide of POC-LEGOS. Development credits go to Thierry Letellier and Florent Lyard.
An open discussion started around this presentation.

Quick start
Get the package. Unpack it and read the readme-1st file for instructions. If you're working within MARETEC or HIDROMOD then map a network drive (say, X:) to \\kepler\DataCenter1\DataCenter\Modelos_2(2)\FES\fes2004data. If not, get the datasets fes2004 here and install them somewhere in your network with read permissions.
Mohid-tide
Here's what the input file should look like (CAUTION: it's longitude latitude null!): CAUTION: The file MUST END with <end_xyz>! Otherwise results will be erroneous. NO BLANK LINES ARE ALLOWED!
longitude latitude null
- Sample input:
<begin_xyz> -61.410 -38.995 0. -61.41 -39.00 0. -61.41001 -38.99 0. -61.41001 -38.7 0. -61.41 -39.38 0. -70.2 -56.2 0. <end_xyz>
- The command line is :
mohid-tide X:\tide.nc input_mohid-tide.dat output.dat 0 2.08
In this example, the input file is called input_mohid-tide.dat. The output file is called output.dat. The data file is called tide.nc and it's path is X:\. The 0 and the 2.08 are respectively the time reference and the water level reference. Change all these parameters accordingly to your situation.

Building fes2004 from scratch under windows
Prerequisites
- Get the WinGSL distribution. Unpack at least the dll.
- Get the netcdf distribution. Unpack at least the dll.
- Get the fes2004 extraction/prediction sotware.
- Get the data file(~600MB) and rename it to tide.nc (or get it at \\kepler\DataCenter1\DataCenter\Modelos_2(2)\FES\fes2004data).
fes2004 vs fes95
Essentially fes2004 contains 4 new relevant tidal components. And it supports higher resolution, allowing extraction of tidal gauges closer to the coast. These two reasons alone make it a very interesting asset to include in Mohid.
