Abstract. Understanding and quantifying the global methane (CH4) budget is important for assessing realistic pathways to mitigate climate change. Atmospheric emissions concentrations of CH4 continue increase, making second most human-influenced greenhouse gas in terms forcing, after carbon dioxide (CO2). The relative importance compared CO2 depends on its shorter atmospheric lifetime, stronger warming potential, variations growth rate over past decade, causes which are still debated. Two...
Abstract. Evapotranspiration (ET) is critical in linking global water, carbon and energy cycles. However, direct measurement of terrestrial ET not feasible. Here, we first reviewed the basic theory state-of-the-art approaches for estimating ET, including remote-sensing-based physical models, machine-learning algorithms land surface models (LSMs). We then utilized 4 2 14 LSMs to analyze spatial temporal variations ET. The results showed that ensemble means annual estimated by these three...
Abstract Accurate quantification of terrestrial evapotranspiration and ecosystem productivity is significant merit to better understand predict the response energy, water, carbon budgets under climate change. Existing diagnostic models have different focus on either water or flux estimates with various model complexity uncertainties induced by distinct representation coupling between processes. Here, we propose a estimate gross primary production that based biophysical mechanism yet simple...
In Europe, three widespread extreme summer drought and heat (DH) events have occurred in 2003, 2010 2018. These were comparable magnitude but varied their geographical distribution biomes affected. this study, we perform a comparative analysis of the impact DH on ecosystem CO2 fluxes over Europe based an ensemble 11 dynamic global vegetation models (DGVMs), observation-based FLUXCOM product. We find that all associated with decreases net productivity (NEP), gross flux anomalies differ...
Cropland redistribution to marginal land has been reported worldwide; however, the resulting impacts on environmental sustainability have not investigated sufficiently. Here we of cropland in China. As a result urbanization-induced loss high-quality croplands south China (∼8.5 t ha
Abstract Lentic systems (lakes and reservoirs) are emission hotpots of nitrous oxide (N 2 O), a potent greenhouse gas; however, this has not been well quantified yet. Here we examine how multiple environmental forcings have affected N O emissions from global lentic since the pre-industrial period. Our results show that emitted 64.6 ± 12.1 Gg O-N yr −1 in 2010s, increased by 126% 1850s. The significance small on mitigating is highlighted due to their substantial rates response terrestrial...
Abstract. Nitrous oxide (N2O) is a long-lived potent greenhouse gas and stratospheric ozone-depleting substance that has been accumulating in the atmosphere since preindustrial period. The mole fraction of atmospheric N2O increased by nearly 25 % from 270 ppb (parts per billion) 1750 to 336 2022, with fastest annual growth rate 1980 more than 1.3 yr−1 both 2020 2021. According Sixth Assessment Report Intergovernmental Panel on Climate Change (IPCC AR6), relative contribution total enhanced...
ABSTRACT Litter decomposition is essential in linking aboveground and belowground carbon, nutrient cycles, energy flows within ecosystems. This process has been profoundly impacted by global change, particularly drylands, which are highly susceptible to both anthropogenic natural disturbances. However, a significant knowledge gap remains concerning the extent drivers of litter across different dryland ecosystems, limiting our understanding its role ecosystem metabolism. Using ARIDEC data...
Genetic diversity data, from Y chromosome and mitochondrial DNA as well recent genome-wide autosomal single nucleotide polymorphisms, suggested that mainland Southeast Asia was the major geographic source of East Asian populations. However, these studies also detected Central-South (CSA)- and/or West Eurasia (WE)-related genetic components in Asia, implying either population admixture or ancient migrations via proposed northern route. To trace time period CSA- WE-related components, we...
Changes in rainfall amounts and patterns have been observed are expected to continue the near future with potentially significant ecological societal consequences. Modelling vegetation responses changes is thus crucial project water carbon cycles future. In this study, we present results of a new model-data intercomparison project, where tested ability 10 terrestrial biosphere models reproduce sensitivity ecosystem productivity at sites across globe, nine which, exclusion and/or irrigation...
Livestock contributes approximately one-third of global anthropogenic methane (CH4 ) emissions. Quantifying the spatial and temporal variations these emissions is crucial for climate change mitigation. Although country-level information reported regularly through national inventories databases, spatially explicit quantification century-long dynamics CH4 from livestock has been poorly investigated. Using Tier 2 method adopted 2019 Refinement to 2006 IPCC guidelines, we estimated at a...
Abstract. Excessive anthropogenic nitrogen (N) inputs to the biosphere have disrupted global cycle. To better quantify spatial and temporal patterns of N inputs, assess their impacts on biogeochemical cycles planet living organisms, improve use efficiency (NUE) for sustainable development, we developed a comprehensive synthetic dataset reconstructing History Nitrogen (HaNi) terrestrial biosphere. The HaNi takes advantage different data sources in spatiotemporally consistent way generate set...
Abstract Global carbon dioxide (CO 2 ) evasion from inland waters (rivers, lakes, and reservoirs) (C) export land to oceans constitute critical terms in the global C budget. However, magnitudes, spatiotemporal patterns, underlying mechanisms of these fluxes are poorly constrained. Here, we used a coupled terrestrial–aquatic model assess how multiple changes climate, use, atmospheric CO concentration, nitrogen (N) deposition, N fertilizer manure applications have affected riverine along...

Abstract Given the important contributions of semiarid region to global land carbon cycle, accurate modeling interannual variability (IAV) terrestrial gross primary productivity (GPP) is but remains challenging. By decomposing GPP into leaf area index (LAI) and photosynthesis per (i.e., GPP_leaf), we investigated IAV mechanisms responsible in a temperate grassland northwestern China. We further assessed six ecosystem models for their capabilities reproducing observed from 2004 2011 that...
Abstract Carbon fluxes at the land‐atmosphere interface are strongly influenced by weather and climate conditions. Yet what is usually known as “climate extremes” does not always translate into very high or low carbon so‐called “carbon extremes.” To reveal patterns of how extremes influence terrestrial fluxes, we analyzed interannual variations in ecosystem simulated Terrestrial Biosphere Models (TBMs) Inter‐Sectoral Impact Model Intercomparison Project. At global level, TBMs reduced net...

Abstract Surface ozone is an important air pollutant detrimental to human health and vegetation productivity, particularly in China. However, high resolution surface concentration data still lacking, largely hindering accurate assessment of associated environmental impacts. Here, we collected hourly ground observations (over 6 million records), remote sensing products, meteorological data, social-economic information, applied recurrent neural networks map (HrSOD) at a 0.1° × across China...
