Abstract Global and regional estimates of daily evapotranspiration are essential to our understanding the hydrologic cycle climate change. In this study, we selected radiation‐based Priestly‐Taylor Jet Propulsion Laboratory (PT‐JPL) model assessed it at a time scale by using 44 flux towers. These towers distributed in wide range ecological systems: croplands, deciduous broadleaf forest, evergreen needleleaf grasslands, mixed forests, savannas, shrublands. A land surface with relatively...
Using high-quality dataset from 12 flux towers in north China, the performance of four evapotranspiration (ET) models and multi-model ensemble approaches including simple averaging (SA) Bayesian model average (BMA) were systematically evaluated this study. The single-layer Penman–Monteith (P–M) model, two-layer Shuttleworthe–Wallace (S–W) advection–aridity (A–A) a modified Priestley–Taylor (PT-JPL). Based on mean value Taylor skill (S) regression slope between measured simulated ET values...
Water availability profoundly and simultaneously affects the water cycle disturbs terrestrial carbon cycle. However, there is currently a lack of knowledge about how carbon–water coupling occurs in response to soil moisture availability, underlying mechanisms. Here, using two kinds observational datasets (i.e., leaf gas exchange ecosystem eddy-covariance), we evaluated normalized water-use efficiency (WUE) measure (g1, "stomatal conductance slope"), explored its dynamic behavior...
Abstract As global warming has progressed, precipitation patterns over arid Northwest China have undergone significant change. In this study, changes in summer (JJA) the eastern part of (ENWC) from 1980 to 2014 were investigated using gridded monthly dataset (CN05.1). The results showed that ENWC experienced a decadal wet‐to‐dry shift 1998. Westerlies played an important role upper atmospheric levels terms water vapour transport; variations principally controlled by input ENWC's western...
Stomatal conductance (gs), the process that governs plant carbon uptake and water loss, is fundamental to most Land Surface Models (LSMs). With global change accelerating, more attention should be paid investigating stomatal behavior, especially in extremely arid areas. In this study, gas exchange measurements environmental/biological variables observations during growing seasons 2016 2017 were combined investigate diurnal seasonal characteristics of gs applicability optimal model a desert...
Abstract Modelling is an important tool in simulating and partitioning evapotranspiration (ET). To obtain realistic of ET, a hierarchical Bayesian (HB) method was used to fit the Priestly–Taylor Jet Propulsion Laboratory (PT‐JPL) model against multi‐tower Flux Network (FLUXNET) datasets. Unique HB its ability exchange information between sites simultaneously estimate species‐and PFT‐level parameters. The results suggested that sensitive parameters varied at both species PFT levels. parameter...
A challenge for the development of Land Surface Models (LSMs) is improving transpiration water exchange and photosynthesis carbon between terrestrial plants atmosphere, both which are governed by stoma in leaves. In module these LSMs, variations parameters arising from diversity plant functional types (PFTs) climate remain unclear. Identifying sensitive among all photosynthetic before parameter estimation can not only reduce operation cost, but also improve usability models worldwide. Here,...
The remarkable climate change has profound impact on the alpine hydrology, it remains unclear to date role of changes in glacier and frozen ground degradation regional streamflow variation. Here, we incorporated mass balance into Budyko framework used elasticity method attribute variation annual for 22 rivers Qilian Mountains (QLM) from 1982 2015. results indicates simulated that considering can explain more than 90% observed at a significance p < 0.01, especially with high coverage....
Knowledge on relationship and determinants of water carbon dioxide (CO2) exchange is crucial to land managers policy makers especially for the desertified restoration. However, it remains highly uncertain in terms use sequestration artificial plantation desert. Here, continuous fluxes were measured using eddy covariance (EC) conjunction with hydrometeorological measurements over an C4 shrub, Haloxylon ammodendron (C. A. Mey.) Bunge, from July 2020 2021 Tengger Desert, China. In entirely...
As a major component of water cycle, the accuracy quantification different precipitation products is critical for evaluating climate change and ecosystem functions. However, lack evidence available to choose precise product in relative applications. Here, solve this limit, we analyze spatiotemporal pattern four products, including CHIRPS V2.0, PERSIANN-CDR, ECMWF ERA5-Land, GLDAS_NOAH025_3H, over China during period 1981–2020, based on five traits (i.e., spatial multi-year average, annual...
This study investigates whether China's real estate industry is limited when facing tightening policies and the impact of government regulation on industry. We employed comprehensive indicators related to Chinese from 2000 2019. The empirical results show that land purchase area, social financing scale industry, taxation negatively prices. Further research shows policy plays a dominating role in alleviating rapid development which suggests centralised could be beneficial for households....

Summary Almost all terrestrial biosphere models (TBMs) still assume infinite mesophyll conductance ( g m ) to estimate photosynthesis and transpiration. This assumption has caused low accuracy of TBMs predict leaf gas exchange under certain conditions. In this study, we developed a photosynthesis-transpiration coupled model that explicitly considers designed an optimized parameterization solution through evaluating four different estimation methods in 19 C 3 species at 31 experimental...
