Session ID#: 14098

Session Description:
Vegetation phenology regulates essential ecosystem functions as well as land surface processes and has important interactions with the climate system. However, the key questions as to what controls vegetation phenology, and how to correctly represent leaf phenology in earth system models remains largely unknown, leaving much uncertainties in future predictions. Our session would like to advance these topics by drawing the recent progress in novel methods and data of phenological observations from species-level to ecosystem-level, new approaches and theories to the underlying drivers, and model development and practices within the context of the Earth system and climate change. In particular, the integration of remote-sensing data from phenocams, UAVs, and satellites with in-situ observations is welcomed. Our session is also looking forward to interdisciplinary studies such as the implications of vegetation phenology on ecological forecasting and policy making.
