Our research areas are on ground, airborne, and satellite remote sensing of vegetation from the leaf level to the global scale with special focus on:
- plant structural and photosynthetic traits
- land surface and carbon uptake phenology
- terrestrial ecosystem primary productivity and greenness
- global change impact on terrestrial ecosystem productivity, and
- terrestrial carbon cycle modelling
We have done, and are doing, remote sensing of vegetation studies at ecological monitoring sites (e.g., eddy covariance tower networks); on improved product development at regional scale (e.g., leaf area index, primary productivity and land surface phenology); and on global change impact assessment on terrestrial ecosystem productivity at regional (e.g., circumpolar land surface phenology and atmospheric CO2 seasonality) and global scales. Besides remote sensing data, we use ground measurements of plant biophysical variables, photosynthetic traits, atmospheric CO2 concentration, eddy covariance CO2 fluxes and plant phenology; gridded climate data records; terrestrial ecosystem carbon cycle models; and Earth System Model (ESM) outputs.
We develop improved remote sensing methods and products for terrestrial ecosystems relevant to the global change studies. Using satellite remote sensing products, ground observations and mechanistic models, we also study the impacts of climate change and variability on terrestrial ecosystems, and related feedbacks to the atmosphere through carbon cycle.
