Interannual variability of net ecosystem productivity in forests is explained by carbon flux phenology in autumn

Aim To investigate the importance of autumn phenology in controlling interannual variability of forest net ecosystem productivity (NEP) and to derive new phenological metrics to explain the interannual variability of NEP. Location North America and Europe.
