FIGURE 2.4 Regional variations in global sea-level rise based on observations from satellite altimetry from 1985 to 2010. The data were corrected for glacial isostatic adjustment, atmospheric barotropic pressure response, and various instrument, media, and geophysical effects. SOURCE: Updated from Shum and Kuo (2011).
FIGURE 2.5 Comparison of sea-level time series from tide gages (1880–2008; blue lines) and from satellite altimetry (1985–1987 and 1991–2010; red lines) after corrections for atmospheric barotropic pressure effects and glacial isostatic adjustment (using the ICE-5G [VM2] model, Peltier, 2004). The thin blue line represents average monthly sea level from global tide gage data. The thick blue line represents yearly sea-level changes from a moving average of tide gage observations, and the shaded area represents the sea-level uncertainty, which reflects the number of gage sites used in the global averages, the number of data points, and the standard deviations of the fit of seasonal signals and the trend of the original gage time series. The thick red line is the yearly averaged altimetry sea-level data. SOURCE: Updated from Shum and Kuo (2011).
