PSMSL data have many applications within

image of IPCC report

The most familiar application is global and regional sea level rise and variability. The PSMSL data set is the main source of information on long term changes in global sea level during the last two centuries. The data have been employed intensively in studies such as those of Intergovernmental Panel on Climate Change (IPCC).

The latest IPCC report, published in 2013, finds that "It is very likely that the mean rate of global averaged sea level rise was 1.7 [1.5 to 1.9] mm/yr between 1901 and 2010, 2.0 [1.7 to 2.3] mm/yr between 1971 and 2010 and 3.2 [2.8 to 3.6] mm/yr between 1993 and 2010. Tide-gauge and satellite altimeter data are consistent regarding the higher rate of the latter period" (www.climatechange2013.org).

This section provides only a brief overview of PSMSL data coverage and applications. For more detailed information, consult a textbook such as one of those listed in the Training and Information web page.
