Ross_Inv_2002 Padman et al. (2003) is a medium-resolution, 1/4o x 1/12o (~10 km) regional model of the entire Ross Sea (see above figure) including the ocean cavity under the Ross Ice Shelf (RIS). The model is optimized by data assimilation of 10 gravimetric tide gauges on the RIS; see Williams and Robinson (1980). Locations are indicated on the above figure. Thus, we expect that model performance is best for prediction of tidal heights under the RIS. For other purposes, e.g., tidal current estimates for the open Ross Sea, models such as our Ross Sea velocity-based inverse model RossTIM (Erofeeva et al. (2005)) may be more accurate.
RossTIM is distributed with a Matlab Graphical User Interface ("GUI") called "TMD" (the Tide Model Driver). TMD can be used to quickly access and browse the model, and to make tide height and current (velocity component) predictions. The TMD package also contains scripted functions for use in batch-mode Matlab processing. For an overview of the GUI and scripts, view or download the README PDF file. For FORTRAN access, please go to the Oregon State "OTIS" web page.
Please reference Padman et al. (2003) for the use of Ross_Inv_2002.
Contact Laurie Padman for advice on which model to use for a particular application, to be added to an update notification list, or for further information on the tide models.
The Matlab-based version of Ross_Inv_2002, plus the TMD Toolbox, can be downloaded by clicking on the links below. The Ross_Inv_2002 file size is ~12 MB. If you prefer to receive the model by CD, please contact us. Ross Sea inverse models will continue to be developed through the life of the AnSlope program. We will also occasionally make updates to TMD.
If you prefer, the model and TMD toolbox can be downloaded from our FTP site, as follows:
