Sentinel for sea-level rise enters testing

Science
The next satellite tasked with maintaining the "gold standard" measurement of sea-level rise is about to enter final testing.Sentinel-6a will pick up from the long-running Jason series of spacecraft when it launches in November 2020.These missions track the height and shape of Earth's oceans with microwave altimeters.Since 1992, the orbiting instruments have observed sea level go up by an average of 3.2mm per year.This trend is accelerating, however. The most recent five-year period, from 2014 to 2019, has witnessed a 4.8mm/yr increase.Sentinel-6a marks the first time this hugely important mission series will fly under the badge of the EU's Copernicus Earth observation programme.It is still a joint venture between Europe (princip...
