+# This J-JOB script runs the radar reflectivity preprocess 
+#      for the FV3-LAM model
+#
+# Description:
+#
+#   RRFS runs a pre-processing task on MRMS radar reflectivity files.
+#   Specifically the process_radarref task executes process_NSSL_mosaic.exe
+#   from rrfs-utl on files 
+#       like MergedReflectivityQC_00.50_${YYYY}${MM}${DD}-${HH}${min}${ss}.grib2.
+#
+# Arguments needed for the corresponding ex-script
+#
