      abstract     = {Passive measurement of sun‐induced chlorophyll
                      fluorescence (F) represents the most promising tool to
                      quantify changes in photosynthetic functioning on a large
                      scale. However, the complex relationship between this signal
                      and other photosynthesis‐related processes restricts its
                      interpretation under stress conditions. To address this
                      issue, we conducted a field campaign by combining daily
                      airborne and ground‐based measurements of F (normalized to
                      photosynthetically active radiation), reflectance and
                      surface temperature and related the observed changes to
                      stress‐induced variations in photosynthesis. A lawn carpet
                      was sprayed with different doses of the herbicide Dicuran.
                      Canopy‐level measurements of gross primary productivity
                      indicated dosage‐dependent inhibition of photosynthesis by
                      the herbicide. Dosage‐dependent changes in normalized F
                      were also detected. After spraying, we first observed a
                      rapid increase in normalized F and in the Photochemical
                      Reflectance Index, possibly due to the blockage of electron
                      transport by Dicuran and the resultant impairment of
                      xanthophyll‐mediated non‐photochemical quenching. This
                      initial increase was followed by a gradual decrease in both
                      signals, which coincided with a decline in pigment‐related
                      reflectance indices. In parallel, we also detected a canopy
                      temperature increase after the treatment. These results
                      demonstrate the potential of using F coupled with relevant
                      reflectance indices to estimate stress‐induced changes in
                      canopy photosynthesis.},
