CARBON FLUXES
Fluxes of trace gases:
measurement involves
eddy covariance where
the change in [CO2] vs
time is correlated with
the mean vertical wind
velocity (due to the
eddies in the wind).

• The technique is a combination of analytical
chemistry (IRGA) and micrometeorological techniques (3D-sonic anemometer).
• Other methods exist for measuring
fluxes
- for leaves and soil closed chambers are
frequently used.
