### Linear Correlations between SST and SIF  
The strengths of the SST-SIF associations vary both spatially and temporally for June, July, August and September (Table 4). Figure 3: Spatial variation of mean SIF across India during the months of (**a**) June, (**b**) July, (**c**) August and (**d**) September indicates a progressive increase from June to September with respect to the growing season.
