The fluctuation seems to be about 5-6 ppm per year, which is equal to
about 2 years.  But Hawaii is in the tropics and doesn't lose a lot of
biomass in "winter," so this effect must be due to something else.
Some local phenomenon.  The actual fluctuations in CO2 levels
attributed to biomass (as evidence from the loss of leaves in the
European deciduous zone) is about .0005%
