TPXO8-atlas

TPXO8-atlas-v1 patching mask: patches of local HR solutions are shown with different colors. 

TPXO8-atlas was first from new generation of atlas solutions. Like older ATLAS solutions new generation solutions combine a basic global solution (i.e. TPXO8, obtained at 1/6 resolution) and high resolution (HR) local solutions. These HR solutions are of various resolution better than 1/6 degree, they were obtained over many years, thus we call them historical. Some of TPXO8-atlas single patches are available here. Unlike all preceding ATLAS solutions, TPXO8-atlas kept higher resolution of most HR solutions rather then averaging them on a coarser grid. This provided dramatic improvement in tidal predictions for coastal areas compared to TPXO8-atlas predecessors. 

TPXO8-atlas has 3 formats:

1. our traditional binary format (OTPS format);

2. netcdf format;

3. TPXO8-atlas-compact (obsolete)

TPXO8-atlas binary/netcdf is set of files with one tidal constituent per file. TPXO8-atlas-compact  format contains all constituents, but at various resolution - i.e. 1/30 resolution where the patches are, and 1/6 resolution for the rest of the Ocean. 

MATLAB toolbox TMD2.5, does not allow for multiple TPXO8-atlas binary files. However a script tpxo_atlas2local.m can be used as plugin. The script makes a multi-constituent local model at given limits collecting data from the single constituent TPXO8-atlas binary files. This multi-constituent binary model can be then read with TMD2.5.

Atlas-compact is readable by special version of OTPS - OTPS2.
