Poyang Lake is China's largest freshwater lake with a high degree of spatio-temporal variation. The has shrunk in size recent years, resulting significant hydrological, ecological and economic consequences. It remains unknown whether the shrinkage trend or regime shift, which importance for policymakers as it may lead to different decisions. This study constructed four-decade record area using multi-temporal satellite images hydrological data. Mann–Kendall analysis revealed decreasing but...
Abstract. Alpine wetland meadow could functions as a carbon sink due to it high soil organic content and low decomposition. However, the magnitude dynamics of stock in alpine ecosystems are not well quantified. Therefore, understanding how environmental variables affect processes that regulate fluxes on Qinghai-Tibetan Plateau is critical. To address this issue, Gross Primary Production (GPP), Ecosystem Respiration (Reco), Net Exchange (NEE) were examined an using eddy covariance method from...
Abstract The climate benefit of blue carbon sequestered by mangrove forests can be partially offset CH 4 emission, but this is rarely assessed using multi‐year high‐frequency measurements. Here, four‐year eddy covariance measurements were used to examine temporal patterns flux and its (i.e., reduced benefit) in a subtropical estuarine China. We found both diel seasonal fluxes mainly driven soil temperature tidal activities, showing greater nighttime emission. On average, one‐tenth CO 2...
Abstract Poyang Lake is the largest freshwater lake in China. It considered as an ephemeral lake—experiencing dynamic seasonal transitions ranging from a surface to wetland conditions. The influence of water level transition on lake‐atmosphere energy exchange can have important consequences for local climate and resource management. Here we study dynamics surface‐atmosphere examine hydrological meteorological controls its partitioning period August 2013 July 2016. Change depth (WD) directly...
Capturing high frequency water surface dynamics via optical remote sensing is important for understanding hydro-ecological processes over seasonally flooded wetlands. However, it a difficult task due to the presence of clouds on satellite images. This study proposed MODerate-resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) Minimum Value Composite (MinVC) algorithm generate daily data at 250-m resolution. The selected pixelwise minimum values from...
Abstract Climate warming induces temporally varying atmospheric water vapor, yet the spatial distribution of opposing trends across global land remains elusive. Here we use monthly ERA5 dataset to discern responses vapor changes rising air temperatures from 1982 2020. Simultaneous increase in both and temperature over approximately three-quarters land, with a median 0.21 mm·K–1, particularly evident tropics. Strong positive are primarily influenced by increasing evapotranspiration...
Missing data is an inevitable problem when measuring CO 2 , water, and energy fluxes between biosphere atmosphere by eddy covariance systems. To find the optimum gap-filling method for short vegetations, we review three-methods mean diurnal variation (MDV), look-up tables (LUT), nonlinear regression (NLR) estimating missing values of net ecosystem exchange (NEE) in time series evaluate their performance different artificial gap scenarios based on benchmark datasets from marsh cropland sites...
Abstract The effects of dams on carbon dioxide (CO 2 ) fluxes in downstream lakes remain elusive. Here we combined eddy covariance observations and random forest models to examine multi‐decadal variations CO the Poyang Lake, largest freshwater lake China, quantified contribution Three Gorges Dam (TGD), world's hydraulic project. We found fluctuated between source sink 1961–2016, tended be post‐TGD period (2003–2016) when vegetation expanded early spatially due declining water level. TGD can...
Remote sensing and land surface models promote the understanding of soil moisture dynamics by means multiple products. These products differ in data sources, algorithms, model structures forcing datasets, complicating selection optimal products, especially regions with complex covers. This study compared different algorithms flagging strategies based on situ observations Anhui province, China, an intensive agricultural region diverse landscapes. In general, outperform remote terms valid...
Mangrove ecosystems can be both significant sources and sinks of greenhouse gases. The restoration mangrove forests is increasingly used as a natural climate solution tool to mitigate change. However, the estimates carbon exchanges remain unclear, especially from restored mangroves. In this study, we observed temporal variations in dioxide (CO2) methane (CH4) fluxes their biophysical controls for 4 years, based on closed-path eddy covariance (EC) system. measurements were conducted wetland...
Compound drought–heatwaves (CDHWs) accelerate the warming and drying of soils, triggering soil compound (SCDHWs) that jeopardize health ecosystems. Nevertheless, behavior these events worldwide their responses to climatic are underexplored. Here, we show a global escalation in frequency, duration, peak intensity, severity SCDHWs, as well an increase affected land area, from 1980 2023. The increasing trends, which particularly prominent since early 2000 s, projected persist throughout this...
Evapotranspiration (ET) is an important component of the water budget. Estimation ET through remote sensing over a mountainous terrain typically obstructed by topographic effects. In this paper, corrections were applied to estimates using surface-air temperature difference-Normalized Difference Vegetation Index ((<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Sensible and latent heat fluxes are important parameters for understanding energy/mass interactions. At present, there a number of methods available to estimate these fluxes, with varying degrees difficulty success. In the present study, we explore use flux variance method surface renewal sensible in two agricultural sites China.

The Priestley–Taylor equation (PTE) is widely used with its sole parameter (α) set as 1.26 for estimating the evapotranspiration (ET) of water bodies. However, variations in α may be large ephemeral lakes. Poyang Lake, which largest freshwater lake China, water-covered and wetland-covered during high-water low-water periods, respectively, over a year. This paper examines seasonal diurnal using eddy covariance observation data Lake. results show that = overall feasible both periods at daily...
