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.
