  • Reads files for Richard Ray's Global Ocean Tide (GOT) models
  • Spatially interpolates tidal constituents to input coordinates

Calling Sequence

from pyTMD.read_GOT_model import read_GOT_model
amp,ph = read_GOT_model(ilon,ilat,directory,model_files,METHOD='spline')

Inputs

  1. ilon: longitude to interpolate
  2. ilat: latitude to interpolate
  3. directory: data directory for tide data files
  4. model_files: list of gzipped model files for each constituent

Options

  • METHOD: interpolation method
    • spline: scipy bivariate spline interpolation
    • linear, cubic, nearest: scipy griddata interpolations
  • SCALE: scaling factor for converting to output units

Outputs

  • amplitude: amplitudes of tidal constituents
  • phase: phases of tidal constituents
