Phenology of short vegetation cycles in a Kenyan rangeland from PlanetScope and Sentinel-2 por Cheng, Yan, Vrieling, Anton, Fava, Francesco P., Meroni, Michele, Marshall, Michael, Gachoki, Stella

“…We further illustrated that PlanetScope series could differentiate the phenology of individual trees from grassland surroundings, whereby tree green-up was found to be both earlier and later than for grass, depending on location. The spatially-detailed phenology retrievals, as achieved in this study, are expected to help in better understanding climate and degradation impacts on rangeland vegetation, particularly for heterogeneous rangeland systems with large interannual variability in phenology and productivity.…”
