I downloaded your file, and using the following NCL code:

ncl 0> z = asciiread("snd20001207.dat", (/1033, 6/), "float")

I was able to successfully read your file into the variable 'z'

ncl 1> print(z)
Variable: z
Type: float
Total Size: 24792 bytes
             6198 values
Number of Dimensions: 2
Dimensions and sizes: [1033] x [6]
Coordinates:
Number Of Attributes: 1
   _FillValue : -999
(0,0) 21000
(0,1) 45.8
(0,2) 215.2
(0,3) 0.00434958
(0,4) 1.48265
(0,5) 2.06844
[...]

If this doesn't help, please post a simplified version of your NCL
code and we'll take a look.

-Rick.
