Regional and Local Tidal Models
For past two decade multiple local and regional tidal solutions were obtained with OTIS. Various altimetric (Topex Poseidon, Topex Tandem, ERS, GFO) and other data sets (i.e. tide gauges, ship born ADCP) were assimilated into various models. Local inverse solutions generally fit the data better for complex topographic areas and in shallow water due to their higher resolution and more coastal data assimilated. Our latest ATLAS global solutions at 1/30 degree resolution exceed the older models quality and resolution in vast majority of locations. However the regional models at 1/12° are still can be useful in the deep ocean, and the local models at higher resolution (i.e. 1/60°, 1km) can still be of comparable quality to TPXO-atlas. Historical local solutions at 1/30° or coarser has been depreciated and are not served anymore.
