Query: Two-dimensional structure functions to characterize convective rolls in
  the marine atmospheric boundary layer from Sentinel-1 SAR images   We study the shape of convective rolls in the Marine Atmospheric Boundary
Layer from Synthetic Aperture Radar images of the ocean. We propose a
multiscale analysis with structure functions which allow an easy generalization
to analyse high-order statistics and so to finely describe the shape of the
rolls. The two main results are : 1) second order structure function
characterizes the size and direction of rolls just like correlation or power
spectrum do, 2) high order statistics can be studied with skewness and Flatness
which characterize the asymmetry and intermittency of rolls respectively. From
the best of our knowledge, this is the first time that the asymmetry and
intermittency of rolls is shown from radar images of the ocean surface.
