Extended Data Fig. 7: Comparisons of VIs, LAI and fesc between the US Corn Belt (upper panels in a) and a nearby forest region in the Northeastern North America (NA, lower panels in a) in August during 2001–2019.

(b) The MODIS EVI, NIRv and fesc were lower over the forest region compared to the Corn Belt, due to the stronger shadows in view. In contrast, the MODIS LAI was higher in the forest region than in the Corn Belt. The corresponding violin plots display the quartile and mean of the target variables, and as well as their distributions. (c) Comparison of VIs, LAI and fesc between the Corn Belt and the nearby forest region in North America in August during 2001–2019 at different levels of GRVI, which was used as a proxy of canopy pigment pools. (d) Comparison of EVI between the Corn Belt and the nearby forest region in North America in August during 2001–2019 at different levels of GRVI and LAI.
