[ncl-talk] discrepancy between greenland ncl map and output from CISM

[Michele Petrini - CITG]

Dear help desk,

I am trying to plot Greenland ice thickness from a CISM simulation. Everything works fine - except that it looks that the ice sheet is a little bit shifted to the right (see attached figure: the small brown ice patch in the North-East should be entirely on land, and that’s the same for other bits in the eastern margin).

The projection settings I am using coincides with those used in CISM (I am using lon/lat and projection settings as in the input file for my simulation), and the resources I set are

  res at mpLimitMode       = "Corners"
  res at mpLeftCornerLatF      = lat(0,0)
  res at mpLeftCornerLonF      = lon(0,0)
  res at mpRightCornerLatF     = lat(ny-1,nx-1)
  res at mpRightCornerLonF     = lon(ny-1,nx-1)
  res at trGridType   = "TriangularMesh"
  res at mpProjection = "Stereographic"  ; Change the map projection.
  res at mpDataBaseVersion     = "mediumres"
  res at mpCenterLonF = -45.0
  res at mpCenterLatF = 70.0
  res at tfDoNDCOverlay      =   True

Do you know the reason for - and if it is possible to solve - this discrepancy? I attach also the contour_movie.ncl file if you want to have a look (the figure attached is just one snapshot).

thanks,
Michele
