Yes, go ahead and send me the modified software that will allow me to
convert from WMO BUFR to little_r. Thanks.
It appears that the NCAR Data Support Section maintains an archive that
updates monthly. I need an archive that updates hourly (I am conducting
WRF-ARW runs to support forecast operations.) If I had software to
convert from netCDF to WMO BUFR, I can at least use the hourly netCDF
-formatted surface observation METAR (Aviation Routine Weather Report)
files for which I have access. Any idea where I can locate software to
convert from netCDF to WMO BUFR?

These data are current and readily available. The surface observations are available at http://dss.ucar.edu/datasets/ds461.0/, while the upper air observations are available at http://dss.ucar.edu/datasets/ds351.0/. The "DS Software" tabs at both locations contain software to convert these files to little_r format. I've modified the implementation of the software I obtained. Let me know if you'd like a copy.
