Nudging Tools in CAM6

Hello everyone,
I want to nudge observational U and V to the CAM6 in CESM2.1.3. The nudging tools are included in the CAM6 user's guide. However, I can't find the directory components/cam/tools/nudging/ in the CESM2.1.3 which is mentioned in the user guide. Who can provide the NudgingTools file from the other CESM version?
Best wishes for you!
Look forward to your repaly!

Nudging has evolved from being a tool to now being a fully integrated part of CAM. Because it is now part of CAM, the nudging namelist is now provided in the cam namelist, like any another parameterization. The cam namelist values can be seen at: CESM2 CAM6.3 Namelist Definitions. Search for "nudging_nl" and that will give you a list of the namelists that are available for nudging and descriptions of each variable. There is also extensive documentation at the top of the actual nudging source code at src/physics/cam/nudging.F90.
