Net uptake of carbon dioxide (CO2) measured by eddy covariance in a 60- to 80-year-old forest averaged 2.0 ± 0.4 megagrams of carbon per hectare per year during 1993 to 2000, with interannual variations exceeding 50%. Biometry indicated storage of 1.6 ± 0.4 megagrams of carbon per hectare per year over 8 years, 60% in live biomass and the balance in coarse woody debris and soils, confirming eddy-covariance results. Weather and seasonal climate (e.g., variations in growing-season length or cloudiness) regulated seasonal and interannual fluctuations of carbon uptake. Legacies of prior disturbance and management, especially stand age and composition, controlled carbon uptake on the decadal time scale, implying that eastern forests could be managed for sequestration of carbon.

Large herbivores limit CO2 uptake and suppress carbon cycle responses to warming in West Greenland (2011, background): “While herbivore exclusion alone has made the system a much stronger C sink, the combined effects of herbi- vore exclusion and warming have further increased GEP to the point where the ecosystem is now compara- ble to the Harvard Forest in terms of NEE (Barford et al., 2001).”
Gross primary production and ecosystem respiration of irrigated and rainfed maize–soybean cropping systems over 8 years (2012, methodology): “To minimize problems related to insufficient turbulent mixing at night, following an analysis similar to Barford et al.

Estimation of daytime ecosystem respiration to determine gross primary production of a mountain meadow (2005, background): “As an alternative to this admittedly difficult and laborious task, it has become popular to extrapolate eddy covariance measurements during nighttime, when FGPP is zero, to estimate daytime Reco using functional relationships with some reference temperature and possibly some measure of soil water av”
