Dear Paul,
thank you for your reply and thank you much more that you have not
written the magic words or wished me good luck.
As I have told you in my phone call, it is unfortunately true. There is
no one who can even convert only one MSU or HIRS/2 data the Level1b to
any other format which can be verified (e.g. ASCII).
I cloud send you a pretty long list of so called "scientists" who have
published something with these data but cannot read even only one (e.g.
the attachment you have got from me). You may get one of yourself if you
make an account in SAA and order some MSU or HIRS/2 from 1991. It would
enough for me to get only one file in ASCII.
Regards
Hossein

This is simply not true. ITPP == International *TOVS* Processing Package. This code has
been around since at least the 1980's and was used to process TOVS (HIRS/2, MSU, and SSU)
level 1b data into level 2 type products.
But, regardless, the ITPP code is written in Fortran77. If you want to read TOVS level 1b
data directly into IDL, I still think you will need to "translate" the Fortran reader code
into IDL code. I haven't ever seen IDL code to read TOVS (in particular, MSU) data (that's
not to say it doesn't exist). The other option is to use the Fortran code to read the
data, process and write what you want out into some intermediate format that is easily
readable by IDL. Either way, you're going to have to write some code. Or pay someone to
write it for you. There is one highly experienced IDL software consultant that frequents
this newsgroup - and I believe he also has a fair bit of experience with
reading/processing satellite data. Maybe that's an avenue you should investigate.
