Hi,<br>My name is Eric Urban. Earlier this summer I posted to the list about ARWpost. Since then I have been doing a C++ rewrite of ARWpost. The first goal of University of South Alabama's CHILI was to modify ARWpost to allow plotting of only the desired fields. With this in mind I hacked together some F90 modules and C++ classes to dictate a new input configuration file format based upon the old namelist.ARWpost format. I seem to have produced a stable product in that respect but have yet to work with any users of ARWpost to extensively test it.<br>
<br>Secondarily, I have started a 'bottom up' approach to rewriting ARWpost in C++. This is because of the somewhat messy structure of ARWpost's original code base. My current task is implementing C++ bindings for WRF I/O with netCDF as the underlying file format. My reasoning for this is because it is hard to make any sort of stability improvement(removing memory leaks) or performance improvement(optmizing I/O) with the current structure of the codebase. The original target language of Fortran 90 was quite advanced when it came out but is quite dated by modern standards and the non-use or absence of modern programming paradigms has resulted in a functional implementation of ARWpost that is not very flexible. I applaud the authors in their efforts in creating a useful program, but unfortunately it has shortcomings. The existing source code base has reasonably high cohesion but extremely high coupling between modules. The latter property has the effect of creating a codebase in which small changes in one module are impossible without a high number of corresponding changes in another. I have other criticisms but they most likely not of interest to the non programmer.<br>
<br> I can safely say that <a href="http://www.mmm.ucar.edu/wrf/WG2/Tigers/IOAPI/index.html#_Toc55177333">http://www.mmm.ucar.edu/wrf/WG2/Tigers/IOAPI/index.html#_Toc55177333</a> is in no way a reflection of the newest version of WRF's IO system. It is rife with errors, omissions, and incomplete specifications. <br>
<br>At the moment I could use any kind of help I can get. I have become a master by neccessity of calling Fortran code from C++. What I really need is someone familiar with ARWpost to help me test it my modified and redesigned version. You would need a linux based system with the PGI compiler to help me in that respect. Also of great help would be anyone familiar with the WRF IO API in its current form willing to answer questions when needed. Or if anyone has more complete,modern documentation from their own work that would be excellent as well.<br>
<br><br><br>Thanks, <br>Eric Urban<br>
