Ozone and its precursors were measured from 15 June 2006 to 14 2007 at an urban site in Shanghai used characterize photochemical oxidant production this region. During the observation period, ozone displays a seasonal variation with maximum spring. Observed nitrogen oxides (NOx) carbon monoxide (CO) reached winter minimum summer. NOx CO has similar double‐peak diurnal cycle, implying that they are largely of motor vehicle origin. Total nonmethane organic compounds (NMOC) concentrations...
Abstract. An operational multi-model forecasting system for air quality including nine different chemical transport models has been developed and provides daily forecasts of ozone, nitrogen oxides, particulate matter the 37 largest urban areas China (population higher than 3 million in 2010). These individual as well mean median concentrations next days are displayed on a publicly accessible website (http://www.marcopolo-panda.eu, last access: 7 December 2018). The paper describes shows some...
Abstract. Precise quantification of the cloud condensation nuclei (CCN) number concentration is crucial for understanding aerosol indirect effects and characterizing these in models. An evaluation various methods CCN parameterization was carried out this paper based on situ measurements activation properties within HaChi (Haze China) project. Comparisons were made by closure studies between using spectra, bulk ratios, cut-off diameters size-resolved ratios. The estimation concentrations...
Abstract. An operational multimodel forecasting system for air quality has been developed to provide services urban areas of China. The initial included seven state-of-the-art computational models and executed in Europe China (CHIMERE, IFS, EMEP MSC-W, WRF-Chem-MPIM, WRF-Chem-SMS, LOTOS-EUROS, SILAMtest). Several other joined the prediction recently, but are not considered present analysis. In addition individual models, a simple ensemble was constructed by deriving statistical quantities...
To better understand the characteristics of ambient abundance volatile organic compounds (VOCs) in Shanghai, one biggest metropolis China, VOCs were measured with a gas chromatography system equipped mass-selective detector (GC/MSD) from July 2006 to February 2010. An intensive measurement campaign was conducted (eight samples per day 3 hour interval) during May 2009. The comparison collected different regions Shanghai shows that concentrations are slightly higher busy commercial area (28.9...
Abstracts. The Northeast China Transect (NECT) has been used to study how water availability influences the composition of plant functional types, soil organic matter, net primary production, trace gas flux, and land-use patterns. We discuss relations species number, C N above-ground biomass with a precipitation gradient interactions practices (grassland fencing, mowing grazing), on basis data from west part NECT. results indicate: 1. grassland communities linear relationship under three...
Observation of surface concentration particulate matter (PM10, PM2.5) and meteorological parameters, including visibility, relative humidity (RH), precipitation, wind speed (WS) from 2008 to 2010 were analyzed in Shanghai, China. The haze events are identified as the following: (1) Severe (visibility < 2 km) occurs frequently when PM10 PM2.5 above 181 115 µg/m3, respectively, with RH between 78%–90% WS ≤ 0.6 m/s; (2) Moderate (2 km visibility 3 greater than 114 µg/m3 96 67%–90% 1.0 (3) Mild...
Abstract. The dynamics of atmospheric CO2 has received considerable attention in the literature, yet significant uncertainties remain within estimates contribution from terrestrial flux and influence mixing. In this study we apply WRF-Chem model configured with Vegetation Photosynthesis Respiration Model (VPRM) option for biomass fluxes China to characterize atmosphere. online coupled is able simulate biosphere processes (photosynthetic uptake ecosystem respiration) meteorology one...
