Abstract The FLUXNET2015 dataset provides ecosystem-scale data on CO 2 , water, and energy exchange between the biosphere atmosphere, other meteorological biological measurements, from 212 sites around globe (over 1500 site-years, up to including year 2014). These sites, independently managed operated, voluntarily contributed their create global datasets. Data were quality controlled processed using uniform methods, improve consistency intercomparability across sites. is already being used...
Abstract. A parameterization scheme for calculating gaseous dry deposition velocities in air-quality models is revised based on recent study results non-stomatal uptake of O3 and SO2 over 5 different vegetation types. Non-stomatal resistance, which includes in-canopy aerodynamic, soil cuticle resistances, parameterized as a function friction velocity, relative humidity, leaf area index, canopy wetness. resistance other chemical species scaled to those their physical characteristics. Stomatal...
A size‐segregated multicomponent aerosol algorithm, the Canadian Aerosol Module (CAM), was developed for use with climate and air quality models. It includes major processes in atmosphere: generation, hygroscopic growth, coagulation, nucleation, condensation, dry deposition/sedimentation, below‐cloud scavenging, activation, a cloud module explicit microphysical to treat aerosol‐cloud interactions chemical transformation of sulphur species clear clouds. The numerical solution optimized...
Daily 24-hour PM2.5 samples were collected continuously from January 1 to December 31, 2010. Elemental concentrations Al Pb obtained using particle induced X-ray emission (PIXE) method. This was the first full year continuous daily elemental composition dataset in Beijing. Source apportionment analysis conducted on this positive matrix factorization Seven sources and their contributions total mass identified quantified. These include secondary sulphur– 13.8 μg/m3, 26.5%; vehicle exhaust– 8.9...
Abstract. Daily PM2.5 (aerosol particles with an aerodynamic diameter of less than 2.5 μm) samples were collected at urban site in Chengdu, inland megacity southwest China, during four 1-month periods 2011, each period a different season. Samples subject to chemical analysis for various components ranging from major water-soluble ions, organic carbon (OC), element (EC), trace elements biomass burning tracers, anhydrosugar levoglucosan (LG), and mannosan (MN). Two models, the ISORROPIA II...
Abstract Understanding the dynamics and underlying mechanism of carbon exchange between terrestrial ecosystems atmosphere is one key issues in global change research. In this study, we quantified fluxes different China, analyzed their spatial variation environmental drivers based on long‐term observation data China FLUX sites published from other flux China. The results indicate that gross ecosystem productivity ( GEP ), respiration ER net NEP ) showed a significantly latitudinal pattern,...
• Carbon (C) and water cycles of terrestrial ecosystems are two coupled ecological processes controlled partly by stomatal behavior. Water-use efficiency (WUE) reflects the coupling relationship to some extent. At stand ecosystem levels, variability WUE results from trade-off between loss C gain in process plant photosynthetic assimilation. Continuous observations C, water, energy fluxes were made at three selected forest sites ChinaFLUX with eddy covariance systems 2003 2005. different...
Abstract. Inferential models have long been used to determine pollutant dry deposition ecosystems from measurements of air concentrations and as part national regional atmospheric chemistry transport models, yet still suffer very large uncertainties. An inferential network 55 sites throughout Europe for reactive nitrogen (Nr) was established in 2007, providing ambient gaseous NH3, NO2, HNO3 HONO aerosol NH4+ NO3− the NitroEurope Integrated Project. Network results modelled inorganic Nr...
Abstract. To investigate the characteristics of PM2.5 and its major chemical components, formation mechanisms, geographical origins in two megacities, Chengdu (CD) Chongqing (CQ), Sichuan Basin southwest China, daily samples were collected simultaneously at one urban site each city for four consecutive seasons from autumn 2014 to summer 2015. Annual mean concentrations 67.0 ± 43.4 70.9 41.4 µg m−3 CD CQ, respectively. Secondary inorganic aerosol (SNA) organic matter (OM) accounted 41.1 26.1...
Abstract. A size-resolved particle dry deposition scheme is developed for inclusion in large-scale air quality and climate models where the size distribution fate of atmospheric aerosols concern. The "resistance" structure similar to what proposed by Zhang et al. (2001), while a new "surface" velocity (or surface resistance) derived simplification one-dimensional aerosol transport model (Petroff al., 2008b, 2009). Compared al.'s model, present accounts leaf size, shape area index as well...
