Mapping Weed Infestation in Maize Fields Using Sentinel-2 data

We find West African SIF to increase during the dry season and peak prior to precipitation, similar to the Amazon. In Central Africa, we find a continental-scale bimodal seasonality in SIF, the minimum of which is synchronous with precipitation, but its maximum is likely less related to environmental drivers. We also find important differences in the seasonality of SIF and VIs, which indicates that VI-based estimates of photosynthesis could be inaccurate as they have been shown to be the Amazon.
