GMSL Rates

CU: 3.4 ± 0.4 mm/yr

AVISO: 3.3 ± 0.5 mm/yr

CSIRO: 3.3 ± 0.4 mm/yr

NASA GSFC: 3.4 ± 0.4 mm/yr

NOAA: 3.2 ± 0.4 mm/yr (w/ GIA)

Frequent Questions

Is sedimentation in the oceans accounted for in the GMSL estimate?
What is the format of the dates in the GMSL time series?
Do you account for plate tectonics in the global mean sea level trend?
What determines the x-intercept (i.e., "zero-crossing" or "base year") of the GMSL plots?
Can I subscribe to the mean sea level estimates?
