Abstract:
Nowadays several global tidal models, most of them freely available for the community, provide tidal sea level heights practically everywhere around the World Ocean, constituting powerful tools for scientists, oceanographers and users of different areas of geosciences. In addition, most of these global models are frequently used to provide tidal heights at the open boundaries of regional high resolution coastal models. This work is an evaluation of the performance of three of the most recognized global tidal models: FES2004 (Lyard et al., 2006), GOT 4.7, an update of GOT00 (Ray, 1999) and TPXO 7.2, an update of TPXO 6 (Egbert et al., 1994; Egbert and Erofeeva, 2002). The tidal harmonic constants from these models are compared to the ones obtained from ten sea level data series gathered at tidal stations located along the Argentine coast (from the Río de la Plata estuary to Tierra del Fuego) and from twenty data series of sea level heights obtained on the crossing of the satellite tracks from the Ocean Topography Experiment (Topex/Poseidon: T/P) on the Argentine continental shelf (in the period 1992-2002). Four semidiurnal constituents (M2, S2, N2 and K2) and four diurnal ones (K1, O1, P1 and Q1) are studied and the corresponding harmonic vectorial differences of observed sea level and altimeter data series are presented and discussed. The main differences between harmonic amplitudes and phases obtained from observations and from global models are detected in coastal waters of the Río de la Plata (a shallow area characterized by a micro tidal regime). Such differences, in general, significantly decrease towards the south, where the tidal range is greater than 10 m and the tide is practically semidiurnal. © 2011 by Nova Science Publishers, Inc.
