CDO

In the above command what i wanted to confirm is that if i execute this command how will it work. What i personally think it will do is that first it will calculate monmean of the input dailydata.nc and then subtract the monmean of respective dailydata.nc from every day. Then it will move to second month like Feb and subtract the longterm monmean of the second month from each day.

I need some critical answers and details about my personal view or am i wrong about that.
