Goodbye Sentinel-1A 🥲. Phase-out starting.

It’s actually good news because the new Sentinel-1D satellite is almost ready to take over and data are to start flowing from mid of this month.

The complete new Sentinel-1 constellation is expected to be in place around early July.
The resulting constellation of Sentinel-1C and 1D will have a 6-day revisit cycle as the original constellation of 1A and 1B but shifted by 1 day.

Antarctica retreat study signals future ice loss.
The ice along Antarctica’s ‘grounding lines’ has been largely stable over the past 30 years – but ice has retreated by more than 40 km in some areas, a new study based on satellite data finds.

"
River deltas are sinking faster than the sea is rising
"
".. river deltas, home to about 5% of the global population .. are experiencing subsidence, which exacerbates the risks from sea-level rise. .. Sentinel-1 mission has captured a decade's worth of data showing land sinking faster than previously thought."

Alarmstufe Rot am Jakobshavn-Gletscher
Satellitendaten zeigen schnellen Eisabfluss des größten Gletschers Grönlands

In diesem Bild ist einer der größten und am schnellsten strömenden #Gletscher Grönlands zu sehen. Die Aufnahme des europäischen Satelliten #Sentinel1 zeigt den #JakobshavnIsbræ an der Westküste #Grönland's. Das Einzugsgebiet dieses Eisstroms umfasst etwa 110.000 Quadratkilometer – dies entspricht 6,5 Prozent des grönländischen Eisschilds. Von der riesigen Gletscherfront des Jakobshavn kalben mehr #Eisberge als von jedem anderen Küstengletscher Grönlands. Auch der Eisberg, der 1912 die #Titanic versenkte, stammte wahrscheinlich vom Jakobshavn-Gletscher.

Wegen seiner enormen Eismassen und schnellen Veränderung steht der Jakobshavn-Gletscher unter ständiger Beobachtung: In regelmäßigen Abständen wird seine Oberfläche von den Satelliten der Copernicus Sentinel-1-Mission abgetastet und kartiert. Dies hat es Forschenden ermöglicht, die Geschwindigkeit dieses Eisstroms und weiterer Gletscher Grönlands in den letzten zehn Jahren genauer zu bestimmen.

Die Farben in dieser Aufnahme verdeutlichen die Resultate der Satellitenmessungen. Demnach fließt das Eis in den weißlich-violett markierten Bereichen des Jakobshavn-Gletschers mit bis zu 50 Meter pro Tag in Richtung Meer. In den roten Bereichen sind es immerhin noch zwischen einem und zehn Meter pro Tag.

Sentinel-1's decade of essential data over shifting ice sheets

Ice velocity is a key parameter in measuring the effects of #ClimateChange. The speed at which #glaciers and #IceSheets move tells us the rate at which they discharge ice and water into the sea, feeding into estimations on future #SeaLevelRise. Data on ice velocity also help to keep track of the break-up of ice sheets, such as calving events or damage to the ice sheets.
Since its first satellite was launched in 2014, the #Copernicus #Sentinel1 mission has provided a step change in the capabilities of polar satellite Earth observation. Its 12-m-long advanced #SAR instrument works in C-band. This makes it a reliable tool for acquiring high-resolution imagery for continuous monitoring and emergency response efforts. It is able to capture data through cloud cover, smoke and during lack of sunlight.
