Greetings! Indeed you are correct: the GRIB2 composites stopped due to NOAA ceasing to send out the N0R products any more: https://www.unidata.ucar.edu/mailing_lists/archives/ldm-users/2021/msg00046.html At this time there are no plans to create GRIB2 composites from DHR or any other products. Depending on your workflow, one alternative is to use the GINI composites: https://thredds.ucar.edu/thredds/catalog/nexrad/composite/gini/catalog.html which can already be handled by many tools (GEMPAK, Python, netCDF-java). Another option is to switch to use the MRMS composites created operationally by NOAA and are in GRIB2 format: https://thredds.ucar.edu/thredds/catalog/grib/NCEP/MRMS/BaseRef/catalog.html Hope this helps!
