The MatLab program TideAnalyser analyses a water level matrix timeseries(i.e., a matrix i cells by j cells by t time) and outputs a harmonic analysis matrix.
It is availiable through SourceSafe OtherTools database.
The program TideAnalyser reads a MOHID HDF5 and returns harmonic component analysis for the entire netcdf waterlevel matrix, writing jpg files to an output directory.
It requires a MOHID HDF5 file. If you have a netcdf file, you can change the code easily in a way that there is a variable named 'data' which has dimensions ixjxt.
If called simply without arguments, it will ask you the data:
- a MOHID HDF5 file with water level data,
- an output directory,
You can specify the input manually by entering them in the following way:
The program will write an TA_data.mat file to the output directory that includes:
- TA_data.mat: the amplitude and phase matrix which is has dimensions ixjxh, with the harmonic components as h.
And it will write in the output directory:
- JPG/PNG files: containing the amplitude and phase maps for each harmonic analysed.
The program takes 3hours to analyse a 250*436*736 matrix, mainly due to harmonic analysis on each cell using T_TIDE package.
T_TIDE: Tide analysis
A t_tide package has to be installed in order to use this script.
