Anton,

I use the TRMM project RSL library for GEMPAK:

> We have an issue with NEXRAD data that Unidata could be helpful with.
> This is in connection with the NEXRAD-ITR project.  We inherited libraries
> to read Archive Level II files from NASA ~ 10 years ago.  Over the years
> we have fixed bugs and made updates to accommodate changes to the headers
> etc..  However, the core software was written by a programmer that is now
> long gone.  These libraries are used extensively by a number of groups in
> the hydrology/hydrometeorology/NASA community, and I am confident that the
> libraries are reading/decoding the data correctly.  Still, it would be
> prudent to check against libraries that were created independently.
> Also, velocity data is not much used, so that has not been tested well.
> To this end we have obtained source codes from the NWS but it is awkward
> to get to the radial reflectivity values, but we did make some
> comparisons.  Overall things look ok, but there are a few things that
> concern us.
> 
> Thus, we are looking for other software to read the data.  The IDV,
> Gempak, and the mosaics (I think you make), all reads the Level II data.
> I have a number of questions
> 
> - Do you use 1 library or are there several at Unidata for reading the
> Level II data?
> 
> - What are the origin of the libraries(s)?
> 
> - Can you bundle up the sources and provide that to us so we can compare
> that with our own.?
> 
> - Do you know of other libraries/people we can contact?
> 
> Thanks
