1. Spectral vegetation index (VI) time series data have been used to monitor and characterize the Earth’s vegetative cover and its dynamics.
2. A new generation of geostationary satellite sensors have been launched during the last decade, providing higher spatial resolution data than before.
3. Studies have reported the utility of higher temporal resolution VI time series data from geostationary satellite sensors in characterizing vegetation seasonal changes.
The article provides a comprehensive overview of the use of spectral vegetation index (VI) time series data for monitoring and characterising the Earth’s vegetative cover and its dynamics from regional to global scales. The article also discusses the recent advancement in understanding vegetation-climate interaction, as well as the limitations posed by cloud cover when using moderate resolution, polar-orbiting satellite sensors. It then goes on to discuss a new generation of geostationary satellite sensors that provide higher spatial resolution data than before, and how they can be used to improve temporal resolution of VI datasets. Finally, it presents several studies that demonstrate the utility of higher temporal resolution VI time series data from geostationary satellite sensors in characterizing vegetation seasonal changes.
