In a second step, we apply the method to reconstructing 2 - D sea level data over 1950 — 2003, combining sparse tide gauge records available since 1950, with EOF spatial patterns from different sources: (1) thermosteric sea level grids over 1955 — 2003, (2) sea level grids from Topex / Poseidon satellite altimetry over 1993 — 2003, and (3) dynamic height
grids from the SODA reanalysis over 1958 — 2001.
