I have generated a wind field estimation map in SNAP using Sentinel-1 GRD Data. Since the radar image is originally inverted during wind field estimation, I am not sure if the produced wind field layer is already terrain corrected. Are the positions and directions of the wind vectors geographically correct? Or are they based on the inverted image? Lastly, what will be the effect of using RD ellipsoidal correction after wind field estimation?
Thank you very much.
