Schematic view of the dynamics of RNEP. The relative net ecosystem productivity (a) and of RLT. The relative light transmissivity (b). The different leaf phenology indicators derived from RLT are presented in the lower part, while the different productivity dynamics indicators derived from RNEP are presented in the upper part. The abbreviations “LF,” “LO,” “CUI,” and “CUD” refer to “leaf fall,” “leaf out,” “carbon uptake increase,” and “carbon uptake decrease,” respectively. The subscripts “_S,” “_E,” and “_L” refer to the “start,” the “end,” or the “length” of the phenological phases mentioned above
