 # Notes for obs_def_radar_mod_nml:
-# (1) Reflectivity limit can be applied to observations and/or state (forward operator).
-# (2) Default lowest_reflectivity values DART will use (if apply_reflectivity_limit = .true.)
-#     is missing_r8 (currently -888888.0) . If you want to use the default, 
-#     delete the line of respective lowest_reflectivity 
-#     ("missing" is not accepted as valid entry here in the namelist).
-# (3) As it is not clear how to assimilate Z (for now), "convert_to_dbz" is always .true.
-#     for Z ... i.e. this namelist value is ignored. If you need to override this,
-#     you must hand-edit obs_def_radar_mod:initialize_module()
+# (1) Reflectivity limit can be applied to observations and/or forward operator.
+# (2) The default constants below match the WRF defaults.  They will need to 
+# be changed for other cases, depending on which microphysics scheme is used.
