Re: 'nan' in 'nc' file

Hello

Thanks for the response, I've just reviewed the example and made my
own ncl program:

begin
  flname = addfile("./no2d3.nc","w")
  v_no2 = flname->NO2

  if(any(isnan_ieee(v_no2))) then
    value = -99.
    replace_ieeenan(v_no2, value, 0)
    v_no2@_FillValue = value
  end if
  flname->NO2=(/v_no2/)
end

But when I ncdump the new nc file, the "nan" has changed to "_", which
is like:

  0.007887535, 0.008808989, 0.009664029, 0.01029408, 0.01089421,
     0.01207584, 0.01365368, 0.01421177, 0.01258714, 0.009963885, _, _, _, _,
     _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,

Would you please tell me how to fix this? Appreciate!
