This image over the coast line of the Netherlands is one of the early radar scans taken by the Sentinel-1A satellite, launched by the European Space Agency (ESA) on 3 April, which is said to be able to provide imagery under any weather conditions, day or night.
You can see Amsterdam on the centre-right side of the image, and in the lower part there’s Rotterdam, with its huge port extending to the left. As well, “Sentinel-1’s radar will also be used for monitoring changes in agricultural land cover – important information for areas with intensive agriculture like the Netherlands”.
