read_netcdf_model.py

• Reads netCDF format tidal solutions provided by Ohio State University and ESR
• Spatially interpolates tidal constituents to input coordinates

Calling Sequence

from pyTMD.read_netcdf_model import read_netcdf_model
ht = read_netcdf_model(ilon,ilat,directory,model_files,type,METHOD='spline')

Inputs

1. ilon: longitude to interpolate
2. ilat: latitude to interpolate
3. directory: data directory for tide data files
4. grid_file: grid file for model
5. model_files: list of model files for each constituent
6. type: tidal variable to run
   • 'z': heights
   • 'u': horizontal transport velocities
   • 'v': vertical transport velocities

Options

• METHOD: interpolation method
  • spline: scipy bivariate spline interpolation
  • linear, cubic, nearest: scipy griddata interpolations
• GZIP: input netCDF4 files are compressed
• SCALE: scaling factor for converting to output units

Outputs

• amplitude: amplitudes of tidal constituents
• phase: phases of tidal constituents
• D: bathymetry of tide model
• constituents: list of model constituents
