• then, specifying the title to
    mytitle= "Sea surface height"
    
  • and modifying the contents of three additional lines further down in the same file to
    v1=  -0.85  ; Low  value for isopleths, disregarded when  nv  is 0 or 1
    v2=   0.85  ; High value for isopleths, disregarded when  nv  is 0 or 1
    nv=  17     ; No. of isopleths, there will be  nv+1  colors
    
    in order to lock the use of contours and color map (such a specification is essential to invoke when executing the multi-figure scripts mcontour.sh, mc-mask.sh) and mlayersection.sh)
  • Then, the following command was issued:

    mcontour.sh 3dMap lon lat MIPOM_ssh.nc ssh 1 25 -40

    Note that 'lon' (2nd argumnet) and 'lat' (3rd argument) are default 2D longitude and latitude names, and could thus have been dropped
    (i.e., mcontour.sh 3dMap MIPOM_ssh.nc ssh 1 25 -40 would have worked here).
    By executing this command, a set of cropped gif images are first produced, these are joined into a gif animation, and the original individual gif frames are deleted. The result is this animation:
