Co Tidal Map

Sea level is an essential climatic variable (ECV). It has been measuring precisely through satellite altimeter. There are several oceanic processes contribute variability of sea level with tide being the major contributor. As tide is periodic and highly predictable, its contribution can be removed from the altimetric measurement for further investigation of sea level variability. A number of procedures developed in the past for predicting tides in the global oceans.

Developed a regional tidal model for the coastal oceans around India based on Princeton Ocean Model (POM). These solutions are reasonably good which we have used for tidal correction of along track data of SARAL-ALTIKa for experimental basis. These digital data can be used to construct time varying tidal elevation at every grid points. Related publications are given in the following references. Co tidal map is hosted on Bhuvan-Cotidal Map.
