Improved Sea Level Reconstruction from 1900 to 2019

This dataset provides global mean sea level and regional sea level reconstructions derived from tide gauge records and satellite altimetry observations. It represents an improved version of the reconstruction by Church and White (2011), utilizing a reduced-space optimal interpolation technique. Enhancements include the incorporation of sea level fingerprints, sterodynamic sea level change patterns, and more comprehensive estimates of local vertical land motion.
