🚀 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. 🌐🔒

🌥️ 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.

💻 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.

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.

Result of a Principal Component Analysis (PCA) created from combined median composites of Sentinel-1 and Sentinel-2 imagery — somewhere in the Sudanese desert.

This PCA composite brings out contrasts between lithologies, structural domains, drainage patterns, and surface materials, highlighting features that are nearly invisible in standard RGB representations.

And yes — it also happens to look stunning.

Result of a Principal Component Analysis (PCA) based on combined median composites of Sentinel-1 and Sentinel-2 satellite imagery — somewhere in the desert of Sudan.

The PCA highlights contrasts between different lithologies, structural domains, and surface materials, revealing subtle geological features that are hard to distinguish in standard RGB composites.

And yes — it also looks simply beautiful.

My experiment with land-cover classification for Calgary using satellite imagery and with a machine-learning model trained on data from another continent.

The results turned out surprisingly good — most classes transferred almost perfectly.
The only noticeable shift was the Forest class: tree and shrub vegetation in the source region differs from Calgary’s, so the model mapped it conservatively here.

Still, the general structure of the landscape was captured very well, and community-level land-cover profiles look consistent.

🛰️ Sentinel-1D joins the Copernicus constellation!

Launched on 4 November at 22:02 CET aboard an Ariane 6 rocket from Europe’s Spaceport in French Guiana, Sentinel-1D completes the first generation of radar satellites within the Copernicus Sentinel-1 mission. 🚀

Providing high-resolution SAR images of Earth — day or night, in any weather — Sentinel-1 supports disaster response, environmental monitoring, maritime safety, and climate science worldwide. 🌍✨
