2 TPXO7.2- GOT4.7 : RMS difference (M2, H > 1000 m) : 0.6 cm TG RMS 33.3 cm Deep Water Tide gauges
3 TPXO7.2- GOT4.7 : RMS difference (M2, H < 1000 m) : 17.8 cm TG RMS 82.8 cm Shallow water 0de gauges
4 Obviously global models will be even more inadequate for coastal tides TPXO7.1 GOT4.7 Comparison of global 0de models to 4 coastal 0de gauges: King Sound, Northwest Australia M2 eleva(on: color = amplitude, contours = phase Tide gauges shown as filled circles
5 Oregon State University (OSU) Tidal Inversion SoZware (OTIS) Ø Varia0onal data assimila0on for barotropic 0des à linear shallow water equa0ons à representer approach à ini0ally applied to global modeling of T/P data (Egbert, Benne`, Foreman, 1994) Ø Subsequently developed into a relocatable system à nested: open boundary condi0ons from larger scale model (eleva0on, velocity, radia0on) à many different types of 0dal data
6 Systema0c applica0on of OTIS to regional and high resolu0on local models Mul0- resolu0on atlas of barotropic ocean 0des (eleva0ons and currents) h`p://volkov.oce.orst.edu/0des/

9 Higher resolu0on local solu0ons: 1 km resolu0on, York Peninsula Reduc0on in RMS misfit for M2: 4 km regional solu0on: cm 1 km local prior solu0on: 5.81 cm 1 km assimila0on solu0on: 4.68 cm à Higher resolution modeling improves tidal model, even without further DA
10 Higher resolu0on local solu0ons: 0.5 km resolu0on, King Sound Reduc0on in RMS misfit for M2: 4 km regional solu0on: cm 0.5 km local prior solu0on: cm 0.5 km assimila0on solu0on: cm à Higher resolution modeling improves tidal model, even without further DA
11 King Sound, N.W. Australia 4 km regional solu0on 0.5 km local solu0on TG RMS (M2) : cm TG RMS (M2) : cm Ø High resolution modeling can greatly improve tidal solutions Ø Difference with TG are still significant
12 But still a potentially large improvement over global models TPXO7.1 GOT4.7 Comparison of global 0de models to 4 coastal 0de gauges: King Sound, Northwest Australia M2 eleva(on: color = amplitude, contours = phase Tide gauges shown as filled circles

28 Total RMS difference between models : 8 constituents ((rms^2)/2) (cm) H < 200 m H < 1000 m H > 200 m H > 1000 m TPXO7.2- GOT TPXO7.2- TPXO7_atlas TPXO7_atlas- GOT Atlas solutions agree better with GOT4.7 at least we are converging! But still some way to go
29 Summary Ø Nested HR DA modeling can significantly improve tidal corrections for coastal altimetry Ø Increasing model resolution can improve the solution even w/o assimilation of further data Ø Have implemented a simple scheme for merging HR solutions into a coarser solution for a larger area Ø Merged solutions retain most of the improvement in accuracy achieved by HR local solutions
30 Prospects Ø Further improve/extend atlas, e.g., more constituents Ø arguably a better approach would be to use a multi-resolution atlas with methods to directly compute smoothly varying tidal corrections on any specified grid Ø Critical need going forward: Improved databases for bathymetry, tide gauges for testing and validation
