About our group

Our research is motivated by the compelling need to understand how climate change impacts ecosystems and society and how to mitigate and adapt to climate change. We strive to address these questions and advance sustainability by combining in-situ measurements, remote sensing, machine learning/AI, and Earth system modeling.

Update on March 30, 2025:

Our global, OCO-2 based SIF product (GOSIF) and GPP product (GOSIF GPP) have been extended to 2024. Both products (0.05-deg; 8-day, monthly, & annual; 2000-2024) can be downloaded from Global Ecology Data Repository. Since 2019, they have contributed to ~450 journal articles.
