Description

In recent years, the use of satellite sensors and near-surface cameras to monitor vegetation phenology at landscape and higher scales has become increasingly common. These technologies provide a means to determine the timing of phenophases and growing season length at high spatial and temporal resolution; coverage that is not attainable by human observers. However, in situ ground observations are required to validate remotely derived phenometrics. Despite increased knowledge and expertise there still remains the persistent challenge of reconciling ground observations at the individual plant level with remotely sensed phenometrics at the landscape or larger scale. This talk aims to explore some of the reasons for these discrepancies.
