Description:Majority of life forms on Earth are built on carbon\, and the e
 xchange of carbon between the biosphere and atmosphere is the fundamental 
 biogeochemical cycle driving Earth’s rich biological activities.  Coinc
 idently\, excessive carbon in atmosphere is also a major source responsibl
 e for today’s biggest environmental issue\, i.e.\, climate change. There
 fore\, a key global effort in recent decades is to quantify and predict th
 e size of the carbon exchange between the biosphere and atmosphere\, which
  is primarily via plant photosynthesis and ecosystem respiration. Accurate
  measure and predictive understanding of global photosynthesis and respira
 tion require fundamental knowledge on ecophysiological processes governing
  leaf photosynthesis and respiration. Yet this leaf-scale understanding is
  not sufficient for global-scale quantification because of challenges in s
 caling-up. Focused on this scaling-up issue\, this talk aims to stimulate 
 discussion on cross-scale and transdisciplinary research that is the key t
 o addressing the challenge in quantitative understanding of global carbon 
 cycle. Specifically\, I will show how different Earth observation products
 \, when combined with ground-based monitoring\, can help constrain carbon 
 cycle simulations in Earth system modeling\, a critical tool for scaling u
 p leaf ecophysiological processes to global-scale carbon cycle quantificat
