File Information

[gmsl,year_vec] = get_gmsl retrieves global mean sea level data from 1992 to present. get_gmsl_ns is functionally identical, but with seasonal signals removed.

INPUTS: none

gmsl = global mean sea level array
year_vec = corresponding years

[sealevels,datearray] = get_gmsl;

The example file provided in the package (global_mean_sea_level_plotter.m) uses get_gmsl and get_gmsl_ns to plot globally-averaged sea levels from 1992 to present and compute a linear least-squares fit for to the data.

Data are retrieved from the University of Colorado Sea Level Research Group website, If you use this data set, please cite the following:
