[ncl-talk] smoothed daily anomalies

[Lyndz]

Dear NCL experts,

Is there a function that I can use to remove the smoothed (2 harmonics)
annual cycle from a one dimensional time series?

I saw this example but for 3 dimensional time series only:

Any suggestions on how to do this in NCL?

Attached is the sample data that I have.
