Deriving land surface phenology indicators from CO2 eddy covariance measurements

no code implementations Ecological Indicators 2013 Alemu Gonsamo a, , Jing M. Chen a, Petra D’Odorico b

Recent progress of CO2 eddy covariance (EC) technique and accumulation of measurements offer an unprecedented perspective to study the land surface phenology (LSP) in a more objective way than previously possible by allowing the actual photosynthesis measurement – gross primary productivity (GPP).
