Representation of MADT et MSLA and their difference to obtain the MDT (Mean Dynamic Topography), a time-independant map.

Absolute dynamic topography maps (MADT) and associated geostrophic velocities for the Kuroshio.

A weak El Niño seems to be coming end of this year. Visualization and comparison with the LAS.

Maps of sea level anomaly and associated formal mapping error : error is much higher outside the ground tracks and smaller merging the four satellites measurements.

The Live Access Server can average the data over a month. The phenomena El Niño is thus visible each November for 12 years -- since first Topex/Poseidon data.

Few examples with greyscales and contours to plot SLA in the Agulhas current.

Comparison between SLA and ADT that give different information on ocean dynamics, especially in the major currents. Application to the Kuroshio and the Gulf Stream.

The Live Access Server allow to compare data, by substraction, overlay, or side-by-side plotting. Application with wind and waves datasets in the North Atlantic.

The Live Access Server allow to impose color scale minima and maxima, depending on what we wish to see.

If you wish to use data time series, make computations and/or plot your figures with your favorite program, the best is to use the OpenDap, the database that provides data to the Live Access Server for its plots.

Water dilatation and contraction due to seasonnal warming and cooling can make sea surface heights vary of about 10 cm between the coldest month and the warmest. Observation with the Live Access Server in the North Atlantic.

Maps of Sea level anomaly variance and average over 2003, in the Antarctic Circumpolar Current area.
