CDO

Hi guys!

Hi guys!

7 years ago, Mr. Mario made the following statement: "Dear all

we calculated trends of air temperature in reanalysis with CDO. But now arises the question how to calculate the significance of these trends with CDO. We have seen that there is a function student-t but for us it is unclear how to use this function and what it does exactly. Does anybody of you know more about this function and how to use it for signifiance tests of trends?

I was excited. It has how to process the t student function in the CDO. Could someone tell me how to do this?

I have two netcdfs.

GPCC.1970-2003.nc

CTRL.1970-2003.nc

Calculating the difference between CTRL and GPCC I have a result. From this result, how can I know how significant the difference in precipitation between the two data is through the CDO?

Can the same be done for anomalies? For example: CTRL eliño phases in relation to the complete GPCC period.

If it is possible to do that at the CDO it would be a revolution in my life.

Thank you!
