@bellingcat.com produced a Radar Interference Tracker (RIT) tool back in 2022, which uses EU #Copernicus #Sentinel1 data to help identify sources of RFI.
However, this can only detect sources that were active during #Sentinel1 data acquisition.

#Copernicus #Sentinel1 data acquired today shows a small vessel on the water around area where tug last reported it position. Hard to tell if this is tug boat MUSSAFAH 2. No visible slick.

Very good article on how good #Sentinel1 #changedetection is in #mapping floodwaters. For a flood in Afghanistan, this methodology was able to detect 5 times the area shown by some products in the Global Flood Monitoring System.

@eumetsat.int Eumetview portal view.eumetsat.int/productviewe..., 1st explosion detected during March 3rd 2026 2:40 scan, followed by another at around 3:50 ↙️⬇️ ??
At 16:55 #EU #Copernicus #Sentinel1 data suggests two vessels still present in region link.dataspace.copernicus.eu/bb88 ↘️
#Copernicus #Sentinel1 acquired data close to likely region today at 4:57 UTC.
Zoom in to see the high backscatter returns of vessels. Debris ?
With LNG on board, will explosion have consumed fuel used to power vessel ?

One of Earth's largest ice avalanches hit the #TibetanPlateau in 2022.
Using #Sentinel1 & #Sentinel2, scientists reconstructed the massive 40 million m³ collapse. From acceleration to impact, satellite data tells the story.

#Copernicus #Sentinel1 acquired data over the Somerset Levels on 28th Jan - water shown in darker colours in this enhanced false colour visualisation.
Using this data, and a DEM of the pre-flooding surface, it should be possible for Environment Agency to work out flood depth and hence flood volume.

Changes over a wide area.
#Copernicus #Sentinel1 data is not able to detect changes in some areas due to signal decorrelation, say changes in vegetation / soil moisture.
Through the use of satellite based radar data, say #Copernicus #Sentinel1, and a digital elevation model of the pre-flooding surface, it should be possible for Environment Agency to work out flood depth and hence flood volume.
This will help determine how many Dutch pumps they need in operation.

Unlike 2014 we now have Dutch pumps.
