The link below provides some details about the format of the
uncompressed data file that should be helpful. You'll need this to
read the file into any type of program/software. You need to
understand the format before you can use the file.<br>

ok, wow. Don’t send the same message 3 times, if the first answers
weren’t complete at least expand and attempt something not just
copy paste the same lines again.

<div class="">as said before .Z means it’s compressed.
gunzip merg_2016020123_4km-pixel.Z will uncompress it. Then
you have a binary file as a small amount of googling would
have told you. </div>
<div class="">The same search would have linked you to various
messages on here and various scripts where other people have
included simple examples of this file type (myself included).
Here is an example of reading and making a simple plot. There
are plenty of examples on how to write netcdf on the NCL
website so you should develop code from there. Most simple
example at bottom of script below. </div>

I need help from someone that can guide me to
