TOPEX/Poseidon and Jason (1,2,3) satellite altimeter data

(Institute of Ocean Sciences, Sidney, BC, Canada)

These web pages provide access to global and regional along-track TOPEX/Poseidon and Jason (TPJ) satellite altimeter plots and data. Initially, we display tidal constituents, a linear sea level trend and two climate indices PDO and MEI. These were calculated using Versatile Analysis VA of 25 years Sep. 1992 – Oct. 2017 of TPJ data in two detiding experiments. The details of VA are explained in the references below, while the lists of analyzed constituents for the two experiments [cb and cv] are given here. An example is shown in the plot below, which also shows 17 predefined geographical regions.

The user interface was designed to plot the amplitudes and phases of the constituents and climate indices, including the linear trend. This interface can be accessed here.
