Sentinel-1D satellite declared fully operational - Spatial Source

The synthetic aperture radar Sentinel-1D satellite will replace its Sentinel-1A sibling and joins its -1C twin to monitor the Earth’s surface.

🚀 Wow, all four Sentinel-1 #satellites are live, but apparently, their groundbreaking achievement is keeping us out with a 403 Forbidden error! 🤦‍♂️ Looks like the only thing they’re observing from space is our inability to access the webpage. 🌐🔒

#ESA has put the fourth #satellite of its #Copernicus #Sentinel1 into orbit. The colored radar images of earth are indeed quite magical to look at.

Sentinel-1D goes live: a milestone for Europe’s radar mission

The Copernicus Sentinel-1D satellite, launched last November, is now fully operational after successfully completing its critical in-orbit commissioning phase.With all four Sentinel-1 satellites having now been deployed, this achievement marks a major milestone for this flagship radar mission – a journey that began more than a decade ago and that has helped pave the way for the future of Earth observation.

🌥️ Pflanzen wachsen nicht nach Kalender. Sie wachsen nach Wetter und Standort. Doch genau das ist oft schwer messbar – vor allem bei Wolken oder schlechtem Licht. Eine ZALF-Studie zeigt jetzt: Radar-Satelliten können helfen. 🛰️

Sie erkennen wichtige Wachstumsphasen zuverlässig. Die Daten kommen von Sentinel-1 und sind regelmäßig verfügbar.

🥳
Here we go: Sentinel-1D is available operationally and data have started to accumulate over the weekend.

Easiest way to access them is via Copernicus Browser, where a filter for Sentinel-1D has been added last Friday.
https://browser.dataspace.copernicus.eu

💻 I took several completely independent datasets and "pitted" them against each other. One of the results is shown in this chart: the more "concrete" (roads, buildings, parking lots) my machine learning model identified in a community, the higher the surface temperature recorded by the thermal sensor.

🔥 The result: Data from different sources confirm one another. The difference in surface temperature between "green" and "concrete" residential areas averages 8–10°C throughout the summer. On certain days, this gap is likely even wider.

📉 This chart shows only established residential communities. If industrial zones were included, the trend would be even more dramatic. While modeling errors certainly exist, the overall physical pattern is undeniable.

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.
