Modelling terrestrial carbon fluxes and crop production with remote sensing and in-situ observations
Wu, Xiaocui (2020-08-20)Plants fix carbon through photosynthesis, sequestering carbon dioxide from the atmosphere and substantially mitigating the climate warming effect induced by anthropogenic CO2 emissions. Terrestrial gross primary production ... -
MULTI-SCALE REMOTE SENSING OF OPEN SURFACE WATER BODY AREA AND QUALITY
Zou, Zhenhua (2019-05-10)Water is one of the most important resources for life. Climate change and climate variability have caused dramatic variations and significant trends in surface water resources, while global population growth and increased ... -
Panic Gardening in the End Times: An Interventional Study of Homescale Gardening on Food Security During Times of Crisis
Vollmar, Robert III (2023-05-12)While the 20th century was characterized by decreasing food insecurity globally due to innovations in food production and distribution, disruptions in both energy availability and climate stability in the 21st century ... -
Precipitation and carbon-water coupling jointly control the interannual variability of global land gross primary production
Zhang, Yao; Xiao, Xiangming; Guanter, Luis; Zhou, Sha; Ciais, Philippe; Joiner, Joanna; Sitch, Stephen; Wu, Xiaocui; Nabel, Julia; Dong, Jinwei; Kato, Etsushi; Jain, Atul K.; Wiltshire, Andy; Stocker, Benjamin D. (2016-12-23)Carbon uptake by terrestrial ecosystems is increasing along with the rising of atmospheric CO2 concentration. Embedded in this trend, recent studies suggested that the interannual variability (IAV) of global carbon fluxes ... -
Quantifying spatial-temporal stability to drought in a semi-arid shortgrass prairie ecosystem
Allen, Eric (2022-05)Drought is known to cause negative ecological impacts in grasslands, with areas prone to drought expected to experience increases in both severity and frequency in the coming years. Cimarron County, Oklahoma is located at ... -
Remote sensing analysis of croplands, woody plant encroachment and carbon fluxes of woody savanna
Wang, Jie (2017-05-12)Since 1990s, much attention has been paid to Land use/land cover change (LULCC) studies because it is an important component of global change. The vegetation change is a critical factor of land cover changes, which interacts ... -
RESPONSES OF COMMUNITY STRUCTURE AND ECOSYSTEM FUNCTIONING TO CLIMATE CHANGE – META-ANALYSIS, MODELING, EXPERIMENTAL STUDY AND DATA-MODEL FUSION
shi, zheng (2015)Observations, experimental studies and modeling endeavors all show that global climate change, mainly increased surface air temperature and associated change in precipitation regime, has caused impacts on plant community ... -
Responses of Terrestrial Biogeochemical Cycles to Global Change – Syntheses and Data-Model Integration
Liang, Junyi (2016-12)Global observations and model simulations show that atmospheric carbon dioxide (CO2) concentrations and surface temperatures have been and will keep increasing. These environmental changes have significant influences on ... -
SATELLITE-BASED CHARACTERIZATION OF CROP TYPE AND PRODUCTIVITY OF AGROECOSYSTEMS: CASE STUDIES IN NORTHEAST CHINA, SOUTHERN AFRICA, AND CONTERMINOUS USA
Jin, Cui (2016-05-13)Agroecosystem, or agricultural ecosystems, is the important anthropogenic ecosystem to meet the human demand for food, fiber, and feed, and it covers approximately 40-50% of the earth’s land surface. Accurate estimates of ... -
A Seasonal to Subseasonal Examination of Synoptic and Local Drivers of Flash Drought
Mesheske, Daniel (2024-05-10)Flash drought is the rapid intensification of drought like conditions. Initiated by meteorological processes that quickly desiccate soil they can be devastating to agriculture and local ecosystems. Flash droughts are driven ... -
Spatiotemporal Changes of Winter Wheat Planted and Harvested Areas, Photosynthesis and Grain Production in the Contiguous United States from 2008–2018
Wu, Xiaocui; Xiao, Xiangming; Steiner, Jean; Yang, Zhengwei; Qin, Yuanwei; Wang, Jie (2021-04-29)Winter wheat is a main cereal crop grown in the United States of America (USA), and the USA is the third largest wheat exporter globally. Timely and reliable in-season forecast and year-end estimation of winter wheat grain ... -
Urban green space distribution in Oklahoma City: A spatial analysis of bio-physical and socio-economic characteristics
Neal, Kevin (2022)Oklahoma City, Oklahoma (OKC) is a fast-growing city undergoing urbanization. Rapid urbanization can lead to neighborhood construction where impervious surfaces are prioritized over urban green space (UGS). Urban green ... -
THE USE OF REMOTE SENSING AND EDDY COVARIANCE TECHNOLOGIES TO CHARACTERIZE CROPLAND, DROUGHT AND LAND MANAGEMENTS AND THEIR IMPACTS ON ECOSYSTEM DYNAMICS
Zhou, Yuting (2017-05-12)With the increasing population, human needs more food, fresh water, and other ecosystem services, which burdens the agricultural and natural ecosystems. Under the background of climate change, meeting these human needs ...
