Abstract. A 6-year-long high-resolution Chinese air quality reanalysis (CAQRA) dataset is presented in this study obtained from the assimilation of surface observations China National Environmental Monitoring Centre (CNEMC) using ensemble Kalman filter (EnKF) and Nested Air Quality Prediction Modeling System (NAQPMS).This contains fields six conventional pollutants (i.e. PM2.5, PM10, SO2, NO2, CO, O3) for period 2013–2018 at high spatial (15 km×15 km) temporal (1 h) resolutions. This paper...
This study seeks to estimate how global supply chain relocates emissions of tropospheric ozone precursors and its impacts in shaping formation. Here we show that goods produced China for foreign markets lead an increase domestic non-methane volatile organic compounds (NMVOCs) by 3.5 million tons 2013; about 13% the national total or, equivalent half from European Union. Production export increases concentration NMVOCs (including some carcinogenic species) peak levels 20-30% 6-15%...
This study introduces a novel vertical bending continuous casting technology for producing thin slabs of pure aluminum and alloys, offering significant advancements over traditional methods. The newly designed equipment optimized process parameters enable the 1070 at speed 1.2 m/min, surpassing conventional direct-chill casting. Comprehensive investigations macrostructure microstructure cast reveal refined equiaxed crystal structure with an average grain size 98 μm, significantly smaller...
Natural and anthropogenic activities affect soil heavy metal pollution at different spatial scales. Quantifying the variability of its driving forces scales is essential for mitigation opportunities. This study applied a multivariate factorial kriging technique to investigate relationship with environmental factors multiple in highly urbanized area Guangzhou, South China. We collected 318 topsoil samples used five types attribution analysis. By kriging, we decomposed total variance into...
Electromagnetic centrifugal casting technique based on magnetohydrodynamic principles has been applied to improve the solidification structure and mechanical properties of a 25Cr-20Ni-Fe-C alloy. The experimental results show that can be controlled by electromagnetic casting. As magnetic flux density increases, macrostructure changes from coarse columnar grains mixed consisting fine curved equiaxed grains, finally, into grains. columnar-equiaxed transition is achieved through fracture...
The quality of Chinese herbal medicine is closely related to its producing region. In order apply mathematical models do a quantitative study on the suitability medicine, it necessary ecological factors and interpolation climatic data, which influence growth. paper firstly studied judgment standard index from points ecology statistics, how calculate optimum range values weight each factor. Secondly, meteorological element data essential in analyzing suitable region spatial distribution...
Abstract. Air pollution in China has changed substantially since 2013, and the effects such changes bring to human health environment been an increasingly hot topic many scientific fields. Such studies, however, are often hindered by a lack of long-term air quality dataset high accuracy spatiotemporal resolutions. In this study, six-year long high-resolution Chinese reanalysis datasets (CAQRA) developed assimilating over 1000 surface monitoring sites from National Environmental Monitoring...
An accurate depiction of temporal and spatial variations in emissions is critical simulating air quality with atmospheric chemical transport models. Most emission processing systems typically use prescribed profiles to allocate anthropogenic based on the assumptions that variance periodical time-independent. However, these are not applicable sources heavily influenced by meteorology holiday activity. In this study, we improved allocation by, first all, developing a dynamic method for...
In order to study the spectral reflectance differences of Glycyrrhizae Radix under different growth conditions and lay foundation for quantitative monitoring remote sensing images, spectra Glycyrrhiza species period varieties regions were measured by a portable spectrometer. The results showed that reflectivity annual G. uralensis was obviously higher than two years plant in visible light band own contents crown layer chlorophyll. pallidiflora near infrared leaf area index content water. red...
A 6063 aluminum alloy thin slab with a cross-section of 260 × 40 mm2 was prepared by vertical bending continuous casting (VC) process. The effects homogenization, hot rolling and subsequent heat treatments on the microstructure properties as-cast slabs as-rolled sheets were investigated scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), field emission probe (EPMA), macro- micro-structure observation tensile tests. results show that structure AA dominated fine uniform...
