Lively Data, 2004

Dec. 15, 2004: What's behind "MADTs"
Representation of MADT et MSLA and their difference to obtain the MDT (Mean Dynamic Topography), a time-independant map.
Nov. 17, 2004: Currents on the slope
Absolute dynamic topography maps (MADT) and associated geostrophic velocities for the Kuroshio.
Oct. 18, 2004: An El Niño this year?
A weak El Niño seems to be coming end of this year. Visualization and comparison with the LAS.
Sep. 15, 2004: Error is part of data
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.
Aug. 16, 2004: El Niño on Novembers
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.
July 15, 2004: colors or contours
Few examples with greyscales and contours to plot SLA in the Agulhas current.
June 15, 2004: SLA vs ADT
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.
May 15, 2004: Comparing winds and waves
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.
Apr. 16, 2004: Saturated color scale
The Live Access Server allow to impose color scale minima and maxima, depending on what we wish to see.
March 18, 2004: Direct access to the data behind the LAS
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.
Feb. 18, 2004: North Atlantic sea level heights over
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.
Jan. 15, 2004: Round the Earth with a current
Maps of Sea level anomaly variance and average over 2003, in the Antarctic Circumpolar Current area.
