Re: LittleEndian help

It should be:
setfileoption("bin","ReadByteOrder","BigEndian")

This says that the input is BigEndian. NCL will
automatically switch to the appropriate endian
of the current machine. On a big-endian machine
no switch will occur.

It is best to always include units for coordinate variables.
lat        = ispan(0,nlat-1,1)*0.25 -  49.875
lat_at_units  = "degrees_north"
finarr&lat = lat
finarr!2   = "lon"
lon        = ispan(0,mlon-1,1)*0.25 - 179.875
lon_at_units  = "degrees_east"
finarr&lon = lon
