Interannual variability of the dynamics of RNEP. The relative net ecosystem productivity (a) and of RLT. The relative light transmissivity (b). The continuous black lines connect the different phenological indicators averaged from 1997 to 2005, while the discontinuous grey lines connect the different phenological indicators averaged from 2006 to 2014. The significant trends observed (indicated by a cross) are described in Table 2
