1. did these Nudging time scales work on both boundary and climatology? If I want to give a strong nudging time scale to boundary and a weak nudging time scale to climatology, how did i do?

2. many people add the climatology nudging, What is the significance? Please give me some typical cases that using clim nudging.

LsshCLM == T ! sea-surface height
Lm2CLM == T ! 2D momentum

LtracerCLM == T T ! temperature, salinity, inert
! Logical switches (TRUE/FALSE) to nudge the desired climatology field(s).
! If not analytical climatology fields, users need to turn ON the logical

! that are needed for nudging. See glossary below for details.
