                         plants with peaks at the red and far-red frequency regions, and it 
                         relates directly to photosynthesis yield and stress. Recent 
                         developments in remote sensing allow us to estimate Sun-induced 
                         fluorescence (SIF) from plants on the Earths surface. In this 
                         study, we have used SIF from the GOME- 2 orbital instrument to 
                         characterize the usual seasonal variation of fluorescence and to 
                         study vegetation responses to anomalous droughts. Results show 
                         that GOME-2 SIF at both frequencies responded consistently to 
                         temperature and precipitation variations observed, and document a 
                         near halving of emissions in response to a drought observed there 
                         from 2012 to 2016. SIF was positively correlated to EVI, NDVI and 
                         GPP but correlations were influenced by vegetation structure and 
                         temporal aspects pertaining to each variable.",
