“…The major limitation for the use of ChlF emission ratio is the larger variations of ChlFv in the RF than in the FRF emission band. Furthermore, some fluorescence parameters, such as F690/F730 and F740/F685, are not very sensitive either to the leaf area and structure of the vegetation or to Chl content (Méthy et al 1991;Takeuchi et al 2002). Field measurements of laser-induced two-wavelength Chl fluorescence under variable light conditions showed a linear influence of direct sunlight on the ratio of F690/F730, whereas the ratio was unchanged under diffuse sunlight (Thoren et al 2010).…”
