Hello,
Tidal solutions coming from Oregon States University used to be available on their website but:
- the website adress changed a few years ago,
- only regional solutions can still be found on their website.
You can find a few regional solutions here:
www.tpxo.net/regional
On this website you can ask to get access to the global solution TPXO but there are conditions to use them. I let you read and write to the owners:
www.tpxo.net/tpxo-products-and-registration
Ask for binary format (not netcdf) if you want to use them with TELEMAC.
Hope this helps,
Chi-Tuan
