Abstract
Abstract Previous studies have suggested that solar‐induced chlorophyll fluorescence (SIF) is correlated with Gross Primary Production (GPP). However, it remains unclear to what extent this relationship is due to absorbed photosynthetically active radiation (APAR) and/or light use efficiency (LUE). Here we present the first time series of near‐surface measurement of canopy‐scale SIF at 760 nm in temperate deciduous forests. SIF correlated with GPP estimated with eddy covariance at diurnal and seasonal scales ( r 2 = 0.82 and 0.73, respectively), as well as with APAR diurnally and seasonally ( r 2 = 0.90 and 0.80, respectively). SIF/APAR is significantly positively correlated with LUE and is higher during…
