TPXO10-atlas

TPXO10-atlas includes gridded to 1/30 degree harmonic constants of the MSL-relative sea-surface elevations and  tidal transports/currents for

TPXO10-atlas is obtained by combining 1/6 degree base global solution TPXO10.v2 and thirty 1/30 degree resolution local patches for all coastal areas, including Arctic and Antarctic. All TPXO10-atlas patches were obtained using consistent bathymetry and boundary conditions from TPXO10 base solution, using the same altimetry data sets for assimilation. 

TPXO10-atlas highlights

TPXO10-atlas-v2 - the latest (release date is Aug 14, 2024) in the TPXO-atlas series:

The figure shows the absolute difference between TPXO10-atlas-v2 and TPXO9-atlas-v5 on logarithmic scale, so the blue color corresponds to ~1mm, green ~1cm, orange ~10cm change in amplitude 

TPXO10-atlas validation

The table shows RMS misfit (cm) to the tide gauges sets, described in:

We provide both TPXO10-atlas and TPXO9-atlas, 1/30 degree resolution in two popular formats:

Note: our netcdf format is different from TMD3 consolidated netcdf format

Since the files are large, we provide one tidal constituent per file. OTPS (nc) does allow to work with multiple single-constituent TPXO9-atlas files. MATLAB toolbox TMD2.5 does not.  Script tpxo_atlas2local.m can be used as TMD2.5 plug-in. The script makes a multi-constituent outcut from the single constituent TPXO-atlas binary files for an area of your choice. This multi-constituent outcut can then be used with TMD2.5

Note: You can convert TPXO9-atlas binary to the TMD3 consolidated netcdf format with a script provided with TMD3.
