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 Erik Noble wrote: > Hi.
