Extended Data Fig. 8: An example light response curve fitted to eddy covariance measurements.
From: Global evidence for the acclimation of ecosystem photosynthesis to light
The y axis is the negative half-hourly net ecosystem exchange (NEE) and the x axis is the half-hourly PPFD. The daytime flux observations in a dynamic window of 2–14 days are used to constrain a light response curve to derive Amax, and every day in the dynamic window is assumed to have the same Amax.
