Recent advances in using Chinese Earth observation satellites for remote
sensing of vegetation
Abstract
Vegetation is an important component of terrestrial ecosystem as it
supports other biological activities through the photosynthetic
production. The biophysical and biochemical parameters of vegetation
retrieved from satellite observations have been used extensively in
studying the physiological states and growing conditions of vegetation
that enabling global vegetation monitoring. Most of vegetation remote
sensing applications using data from MODIS, Landsat, and Sentinel,
though it would be beneficial, from the user perspective, to have an
even more diverse data sources that not only secure data sustainability
in case satellite retirement or sensor failure, but also enables
research opportunities such as multi-sensor data fusion/integration and
multi-angle remote sensing that can take advantage of observations
acquired from different spaceborne sensors. In this regard, it would be
worth to explore the potential of the large number of Chinese Earth
Observation Satellites (CEOS) that have been put into orbit over past
decade. Here we summarized the recent advances in applying CEOS remote
sensing of vegetation and its associated applications. We focused on the
uncertainty and limitations for retrieving several commonly-used
vegetation parameters by critically examining the case studies conducted
over different vegetation types. Suggestions for research opportunities
that can benefit from the additional data from CEOS are also provided.
The hope is to provide the community an overview of what could be useful
to their specific ecological, environmental and global change studies by
leveraging the growing data volume from the orbiting CEOS sensors.
