<div>Hi<br></div><div><div id="gmail-m_52432057665960063yiv0256048078"><div>
<p>I don't have such a script. But, I have read similar data in odd
formats. What was helpful in the absence of NCL code (which IS
tedious for weird text) is to preprocess the data in a scripting
language, sed/awk, Perl etc. Perl I am most familar with and it is
very flexible when reading values, spaces, etc. It was made for
text processing! :) But other langauges also can do this. <br clear="none">
</p>
<p>You then write it out in a way that NCL can read more easily.</p>

<div dir="ltr">If I remember correctly, TTAA

data (1000, 925, 850, 700, 500, 400, 300,

(temperature, wind and humidity) for each
level are coded in these files. I'm not much
familiar with these codes, however, each
