Re: longitude is wrong

*You*, not NCL, specified the latitude and longitudes of the grid.
NCL is plotting using the lat/lon you provided!!

======================================
You say the plot is "wrong" but you do not state
what is "wrong". We are not familiar with all the assorted HDF products.
You must be specific when posting to ncl-talk.

======================================

Also since the grid is 720 x 1440.
The grids span (say)

lat: -89.5 to 89.5 [ or 89.5 to -89.5]
lon: -179.5 to 179.5 [or 0.5 to 359.5]

===

lat=fspan(-90,90,numlat) ; NO!!!
lon=fspan(-180,180,numlon) ; NO!!

lat@units="degrees_north"
lon@units="degrees_east"

data&lat = lat
data&lon = lon

Maybe try:

lat=fspan(89.5,-89.5,numlat) ; reverse lat order

or
  lon=fspan(-179.5, 179.5,numlon)

or
lon=fspan(0.5,359.5,numlon)
