Regional MSL trend (1993-2014)

Printer-friendly versionSend by emailRegional MSL trend (1993-2014)

 Although the global trend indicates a rise in the mean level of the oceans, there are marked regional differences that vary between -10 and +10 mm/year. A map of these regional trends is one of the Sea Level CCI products, obtained from multi-mission SL_cci FCDR, then gridded using radar altimeter data from 1993 until 2014. This product enables the local slopes to be estimated with a very high resolution (1/4 of a degree cartesian grid). Isolated variations in MSL are thus revealed, mainly in the major ocean currents.
