Other claims from this paper (6)
- Observation Spectral signals were crop specific and sensor independent.
- Method / resource fAPAR models fitted better than fCover models.
- Method / resource Model fits were best for maize, then wheat and potato.
- Observation S2 fAPAR variability decreased through the growing season.
- Method / resource The upward endpoint corresponded to canopy closure, and maxima to flowering and fruit development.
- Recommendation More frequent revisits were beneficial for detecting short crop stages.
