[1] There is no general interpolation formula that can
be accurately estimate the true amplitude of the
annual cycle given monthly data. The user must provide
more information.
[2] Remember the the monthly mean actually applies to the
center of 'mass' of the observations. That would be the
mid-day of the month.
