Global Sea-Level Change, 1992 to 2017

ECCO sea-surface height change from 1992 to 2017
land NASA VEDA COG
In plain English

What it measures. A worldwide map of how much the height of the ocean surface changed between 1992 and 2017, calculated as the difference between those two years.

How it's made. Produced by the ECCO ocean model, which blends many ocean measurements into a consistent global estimate of ocean circulation and climate.

How & where you'd use it. Helps scientists see where seas rose or fell over 25 years as the climate warmed.

Official description

Gridded global sea-surface height change from 1992 to 2017 from the Estimating the Circulation and Climate of the Ocean (ECCO) ocean state estimate. The dataset was calculated as the difference between the annual means over 2017 and 1992, from the 0.5 degree, gridded monthly mean data product available on PO.DAAC (https://podaac.jpl.nasa.gov/dataset/ECCO_L4_SSH_05DEG_MONTHLY_V4R4).
