In short: It’s not an apocalypse; it’s a data corrective. It proves that the engine room of our planet is a highly active, rapidly changing environment, and it took a constellation of advanced satellites sixteen years of data-crunching to finally reveal what happened right under our feet.

Insights into Earth’s molten outer core from space

The liquid iron in Earth’s outer core doesn’t always behave as expected. When it changed direction in an unexplained way, ESA satellites provided data on the direction of flow, helping scientists gain better insight into the dynamics at the centre of our planet.

“During recent storms, satellites recorded ocean waves averaging nearly 20 metres high – the largest ever measured from space. Moreover, satellite data now reveal that ocean swells act as storm ‘messengers’ - even though a storm may never make landfall, its swell can travel vast distances and bring destructive energy to distant coastlines...
This record merges data from satellites such as #SARAL, #Jason3, #Copernicus #Sentinel 3A and 3B, Copernicus #Sentinel6 Michael Freilich, #CryoSat and #CFOSAT…”

Grönland: subglaziale Überflutung bricht durch die Oberfläche der Eisschicht

Anhand von Daten mehrerer Erdbeobachtungssatelliten, darunter CryoSat der ESA und die Missionen Copernicus Sentinel-1 und Sentinel-2, haben Forschungsteams entdeckt, dass eine enorme Flut unter dem grönländischen Eisschild mit solcher Wucht nach oben gedrückt hat, dass sie den Eisschild aufgebrochen hat und eine gewaltige Menge Schmelzwasser durch die Eisoberfläche gerungen ist.

Im langjährigen Mittel sind etwa 7 % der globalen Ozeanfläche von #Meereis bedeckt. Satelliten wie #CryoSat-2 (ESA) erfassen aus über 700 km Höhe kontinuierlich hochaufgelöste Höhenprofile der Meereisoberfläche. Diese #Satellitendaten ermöglichen die Analyse von Veränderungen und Trends und sind grundlegend für das Verständnis klimarelevanter Prozesse in den #Polarregionen. Radaraltimeter messen präzise den Abstand zwischen Satellit und Eisoberfläche. #Klimaforschung

ESA and NASA deliver first joint picture of Greenland Ice Sheet melting

Global warming is driving the rapid melting of the Greenland Ice Sheet, contributing to global sea level rise and disrupting weather patterns worldwide. Because of this, precise measurements of its changing shape are of critical importance for adapting to climate change.Now, scientists have delivered the first measurements of the Greenland Ice Sheet’s changing shape using data from ESA's CryoSat and NASA's ICESat-2 ice missions.

Greenland Ice Sheet Shrinking at Incredible Rate

"Greenland ice sheet seen melting in real-time from Earth orbit
Agreement from two satellites CryoSat-2 and ICESat-2m. Between 2010 and 2023, Greenland lost 563 cubic miles (2,347 cubic kilometers) of ice, which is enough to fill Lake Victoria, Africa's largest lake."
