Short summary

The development of eddy-covariance measurements of ecosystem CO₂ fluxes began a new era in the field studies of photosynthesis. The interpretation of the very variable CO₂ fluxes in evergreen forests has been problematic especially in seasonal transition times. We apply two theoretical needle-level equations and show they can predict photosynthetic CO₂ flux between the atmosphere and Scots pine forests. This has strong implications for the interpretation of the global change and boreal forests.
