Scatter plots between measured and estimated biochemical contents from PROSPECT PDb (PROSPECT D considering the brown pigment content). The solid line corresponds to the 1:1 line. a Chlorophyll and carotenoid content (\(C_{\text{abc}}\)); b chlorophyll content (\(C_{\text{ab}}\)); c water content (\(C_{\text{w}}\)); d dry matter content (\(C_{m}\)). The dashed line is the best linear fit corrected from the offset. Green and red points correspond to measurements achieved at two nodes (April) and grain filling (June) stages respectively
