[ncl-talk] Removing annual cycle and nth harmonics from one dimensional data

[Lyndz]

Dear NCL-Experts,

I have daily rainfall data from 1979-2017.

I would like to:

[a] Remove the annual cycle
[b] Then remove the seasonal cycle (3rd harmonics).

I saw this function in NCL which computes the daily climatology first
before getting the anomalies (including smoothed anomalies).

*http://www.ncl.ucar.edu/Document/Functions/Contributed/calcDayAnomTLL.shtml
<http://www.ncl.ucar.edu/Document/Functions/Contributed/calcDayAnomTLL.shtml>*

But this can only be applied for *time x lat x lon data*.

Is there an equivalent function of one-dimationsal (time series) data like
this?
If none, do you have any suggestions on how I can do this in NCL?


I'll appreciate any help.
