Mechanistic approach to remote sensing of GPP

The project “Towards a mechanistic approach to remote sensing of gross primary production (GPP)” was a 3 year postdoctoral project funded by the Academy of Finland (Jan 2011- Dec 2013) (PI. Porcar-Castell). We evaluated the potential of integrating different sources of optical data to interpret seasonal variations in photosynthetic light use efficiency and gas exchange. Although a part of the data is still being analyzed, one of the main outcomes was that the integration of PRI and fluorescence data at the seasonal scale is complicated by the decoupling between PRI and non-photochemical quenching (NPQ) under severe cold stress (Porcar-Castell et al. 2012, Oecologia).
