[ncl-talk] How to get explained variance from spectra

[Lyndz]

Dear NCL-experts,

I have a sample data that I attached here and below is the script that I
used to plot the spectra.

I found significant peaks between 5-10 (days).

I would like to ask how to estimate the fractional variance of
total rainfall variability explained by this 5-10 days ISO. Im not sure if
this can be estimated from the spectra. If not, any suggestions on how to
do this NCL?
