Sensitivity of Estimated Total Canopy SIF Emission to Remotely Sensed LAI and BRDF Products
Relationships between tower-based GPP and TROPOMI RSIFtotal calculated with different combinations of RedV and . RedV was calculated with MCD43 (first row), VNP43 (second row), and MCD19 (third row). was calculated with MCD15 (first column), VNP15 (second column), and CGLS (third column). For simplicity, these sites were classified into two types: C3 and C4 plants, with following number indicating . All regression models are statistically significant ( value < 0.001).
