How to calculate "Standard deviation (STD)" by CDO?

Question

Like, I am having "observed data (obs.nc) and model data (model.nc)". Inside the file have monthly averaged wind speed and the duration of data is 32 years. As a new user, I do not know how to calculate the "Standard deviation" by CDO? Could you guide us on how to compute the "Standard deviation" by CDO? A great thank you in advance.
