Nudging namelist confusion

[wangjm]

Hi, I am confused about the two parameters "gfdda_interval_m" and "guv", how to understand "guv"? do the have the relationship like this: "gfdda_interval_m*60 =1/guv "? however, the example from Steps to run analysis nudging: ( the following picture) seems to have no such relationship. Thank you.

Hi,
Apologies for the delay in response. I don't believe the two parameters are related.
gfdda_interval_m is simply the time interval between your nudging input data (e.g., every 180 mins)
guv is the nudging coefficient for u/v velocities (per second)
