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. |

[PDF] Group news: 2024: November: Jingfeng is the winner of the UNH Faculty Excellence in Research Award in 2024. The university created a video to honor him [YouTube video: UNH Faculty Excellence: Jingfeng Xiao] October: Our work is featured by USDA Forest Service: The Future of Water: A New Tool Helps Show the Relationship Between Climate, Plants, and Water Our projections of future water yield with climate and vegetation change for each HUC-8 watershed in the CONUS (2008-2099) are available for visualization online: https://usfs.maps.arcgis.com/apps/dashboards/5055d33b5553470c960f5648f2077ee9. September: Jingfeng and collaborators published a paper in Journal of Forestry: Do Experimental Forests and Ranges of the southeastern United States represent the climate, ecosystem structure, and ecosystem functions of the region? [PDF] Our collaboration with Dr. John Kim at USDA Forest Service has led to the funding of a two-year project: Projecting Future Net Primary Productivity and Vegetation Shifts in Alaska Using a Dynamic Vegetation Model Under Climate Change Scenarios ($339,215). Henrique will work on this project starting from March 2025. August: Jingfeng presented research results at the 11th International Carbon Dioxide Conference (ICDC) in Manaus, Brazil. Henrique's paper titled Climate and vegetation change impacts on future conterminous United States water yield is published in Journal of Hydrology. [PDF]. The MC2 projections of potential vegetation (vegetation type and LAI) and WaSSI projections of water yield, evapotranspiration (ET), and soil moisture for the CONUS, and the adapted WaSSI model code can be downloaded from our data depository. Jingfeng gave a talk at the USCCC Annual Meeting. The title of the tlak is: Towards understanding diurnal cycling of ecosystem processes acros the globe. June: Our collaborator Dr. Junjie Liu led a nice paper in Science Advances: The reduced net carbon uptake over northern hemisphere land causes the close-to-normal CO2 growth rate in 2021 La Niña. Our GOSIF GPP product contributed to this work. [PDF]. May: Our global, OCO-2 based SIF product (GOSIF) and GPP product (GOSIF GPP) have been extended to 2023. Both products (0.05-deg; 8-day, monthly, & annual; 2000-2023) can be downloaded from Global Ecology Data Repository. Since 2019, they have been used in ~270 journal articles. April: Our collaborators Drs. Shengli Tao and Zuirui Ao led a paper in Science. We find that among 82 major cities across China, 45% are subsiding >3 mm per year, and 16% are subsiding >10 mm per year. The sinking of cities is likely due to groundwater withdrawal and building weight. [PDF] Weizhi, a former visiting scholar, published a nice synthesis study on carbon fluxes of China’s coastal wetlands and impacts of reclamation and restoration in Global Change Biology. [PDF] Jingfeng gave an invited talk on monitoring vegetation phenology using solar-induced chlorophyll fluorescence at the International Assocation of Landscape Ecology-North America (IALE-NA) annual meeting in Oklahoma City. March: Jingyi published a paper on dryland evapotranspiration estimation with remote sensing solar-induced chlorophyll fluorescence in Remote Sensing of Environment [PDF]. This is mainly based on her PhD work. January: Our Machine learning and FLUXNET based Carbon and Water Fluxes (MF-CW) product is available online. MF-CW is a 0.5-degree gross primary production (GPP), evapotranspiration (ET), and water use efficiency (WUE) product for the globe (1982-2016) and is upscaled from FLUXNET observations. The data can be downloaded from our Global Ecology Data Repository.
