Actually I’m trying to generate wind direction and velocity using sentinel-1 images. But I’m having some problems: after processing the image, using SNAP, I have been obtained this kind of image (see file attached). In this image appears wind direction (with ambiguity) and velocity in m/s.
When I tried to export these parameters those that are exported are in the .txt file attached.export_wind_field_estimation_TRANSECT_sentinel.txt (152.5 KB)
My questions are:
1 - How to eliminate the ambiguity in order to obtain the wind direction?;
2 - How to extract the wind velocity from these image and export it as a .txt file?
