Relationships between tower flux monthly averaged GPP and (a) RSIFobs (C3: ; C4: ) and (b) FRSIFobs (C3: ; C4: ). For simplicity, these sites were classified into two types: C3 and C4 plants, with following number indicating the coefficient of determination (). All regression models are statistically significant ( value < 0.001).
