To know the Sentinel1 images provided by Polar View this spring I had created these composite maps (24 days, so 4 series of 6 days), maps divided into West Antarctica, East Antarctica (Australia) and East Antarctica (Africa).
One can notice that some images are provided only by a satellite and therefore have a period of 12 days and not 6 as the others.
Furthermore I have considered two 12-day cycles to cover the possible omissions of Polar View.
I am posting them in the event that you may find them useful
