I have tried to test the SNAP 6.0 WorldWindAnalysisView tool on a Sentinel-1 Adriatic scene and encountered two problems:
1 - Max OWI Wind Speed appears to be set at 10 m/s. It can be lowered, but cannot be increased; some forceful wind episodes would need 20 m/s top, or even higher.
2 – Wind vectors, when selected, point to “180-degrees wrong” direction: towards the eastern coast, instead towards the open sea. The bora wind is absolutely reliable test here: it blows from the coast to the sea, never the other way around.
It does not look like something I can fix myself …
