Solar Induced chlorophyll Fluorescence (SIF) is a direct measure of photosynthesis rate as it is emitted by the photosynthetic system. This paper reports a method to model SIF over India by assimilating spatial inputs (LAI, Chlorophyll content etc.) into FluorMOD leaf and canopy model. Modelled SIF was then compared to Orbiting Carbon Observatory (OCO-2) SIF observations from September 2014 to August 2015. Modelled SIF at 757 nm averaged over the country varied between 0.18 to 0.33 W m<sup>-2</sup> sr<sup>-1</sup> μm<sup>-1</sup> whereas SIF at 771 nm varied between 0.10 to 0.19 W m<sup>-2</sup> sr<sup>-1</sup> μm<sup>-1</sup>. OCO-2 observed SIF at 757 nm averaged over the country ranged from 0.18 to 0.42 Wm<sup>-2</sup>sr<sup>-1</sup>μm<sup>-1</sup>. Fairly good agreement (r=0.77, p<0.01 at 757nm; r=0.71, p<0.05 at 771 nm) was observed between modelled and observed SIF except for summer months of April and May. This paper presents a new approach to upscale a leaf and canopy level model to estimate SIF over entire country.
