¥What we measure: Net Ecosystem Exchange
¥(the flux of CO2 across an imaginary plane above the
canopy)
¥
¥But: NEE cannot be directly parameterized
¥NEE =
Photosynthesis - Respiration
¥
¥The model
(or observation equation) must ÒtransformÓ the observation (NEE) into physically modeling components.
¥
¥This is
neglecting complex but different processes such as fire and forest harvest.
