About our group

Our research is motivated by the compelling need to understand the impacts of climate change and human activities on the Earth’s biosphere and the feedbacks to the climate. We strive to answer major science questions on global carbon/water cycles, climate-vegetation interactions, ecosystem dynamics, and coupled natural and human systems. We combine terrestrial biosphere modeling, remote sensing, field measurements, upscaling, model-data fusion, and statistical analysis to answer these science questions.

Group news:

2017:

September:

Xing's manuscript on chlorophyll fluorescence has been accepted by Remote Sensing of Environment. This study is timely by demonstrating that chlorophyll fluorescence observed by the Orbiting Carbon Observatory-2 (OCO-2) is strongly related to flux tower GPP in temperate forests. This is the first time that space-measured fluoresence is linked with photosynthesis at the ecosystem scale for temperate forests.

Jingfeng attended the 5th Integrated Land Ecosystem-Atmosphere Processes Study (iLEAPS) Science Conference at Oxford, UK and presented our recent work on the constraining of ecosystem carbon uptake using new satellite data observations (J. Xiao and X. Li).

We had a group dinner at Bella's Casual Dining on the evening of September 17th (Sunday).

Ms. Xiaojuan Huang (visiting PhD student) and Drs. Haibo Wang and Weizhi Lu (visiting scholars) joined our group and will conduct research in global ecology during their one-year stay. Welcome and have a fruitful year!

August:

Jingfeng attended the 12th International Congress of Ecology in Beijing, China (August 21-25) and presented our new work on OCO-2 fluoresence (J. Xiao and X. Li).

Jingfeng attended the 14th United States-China Carbon Consortium (USCCC) annual meeting at Taiyuan, China (August 18-20th). He led a breakout discussion session on a potential synthesis paper and also presented our new work on terrestrial photosynthesis.

July:

Jingfeng serves on a NASA review panel in Washington DC.

April:

Dr. Baolin Xue's paper on global patterns of woody residence time is accepted by Global Biogeochemical Cycles.

March:

Jingfeng serves on a review comittee of the National Academies of Sciences, Engineering, and Medicine.

Feburary:

Dr. Weizhi Lu's synthesis paper on wetland carbon fluxes is published in Global Change Biology.

Dr. Junmei Tang's paper titled Impacts of land use and socioeconomic patterns on urban heat island is published in International Journal of Remote Sensing.
