Vegetation greenness and photosynthetic phenology in response to climatic determinants
Frontiers in Forests and Global Change, 2023 Vegetation phenology is a key indicator of vegetation-climate interactions and carbon sink changes in ecosystems. Therefore, it is very important to understand the temporal and spatial variability of vegetation phenology and the driving climatic ...

International Journal of Applied Earth Observations and Geoinformation, 2021 Satellite-derived phenology (or apparent phenology) is frequently used to illustrate changes in plant phenology (i.e. true phenology) and the effects of climate forcing. However, each study uses a different method to detect phenology.
