These consist of a well at the centre of each circle, which supplies water from underground aquifers to rotating sprinklers.

Olivier D'Hondt 🛰️🌍🌱<p>It's hard to get proper visualizations of SAR imagery due to high image dynamics. I have spent quite some time tweaking this one, which represents the parameters of the dual-pol H-alpha decomposition on the new Sentinel-1C sensor!

In this multi-temporal false-color composite, the yellow line is the rough and exposed ice edges left in the wake of a ship breaking through the much smoother sheet ice which appears black. The blue features in the water are ships that were acquired in summer time images, ghosts of shipping past.</p>

Still concerning the L.A. wildfires observed through interferometric coherence evolution, a descending pass #Sentinel1 A image was acquired ~12hours after the ascending one.
So, here is a twelve-days interferometric coherence evolution 12 hours apart.
There is certainly slope effects due to incidence angle variation but some losses of coherence in twelve hours are clearly visible.
