Unit of variance in spectral analysis

Hi users,
The vertical axis of the spectral analysis examples (http://www.ncl.ucar.edu/Applications/spec.shtml) are labelled "variance". What is the unit? I'd think it represents the relative contributions of the different frequencies to the overall variance of the time series. But how is it scaled in ncl, as percents?
Thanks in advance.
