Abstract. Numerical air quality models (AQMs) have been applied more frequently over the past decade to address diverse scientific and regulatory issues associated with deteriorated in China. Thorough evaluation of a model's ability replicate monitored conditions (i.e., model performance or MPE) helps illuminate robustness reliability baseline modeling results subsequent analyses. However, numerous input data requirements, configurations, evolution themselves, no two AQM applications are...
Abstract. The outbreak of COVID-19 promoted strict restrictions to human activities in China, which led a dramatic decrease most air pollutant concentrations (e.g., PM2.5, PM10, NOx, SO2 and CO). However, an obvious increase ozone (O3) was found during the lockdown period urban areas China. In this study, we conducted field measurements targeting its key precursors by utilizing novel proton transfer reaction time-of-flight mass spectrometer (PTR-TOF-MS) Changzhou, is representative Yangtze...
Hysteresis model predictive control (HMPC) is a variant of finite-control-set control, which mainly developed for high-power applications. In this paper, the HMPC scheme proposed to grid-connected two-level voltage source inverter with an inductive-capacitive-inductive (LCL) filter. To ensure stable operation system, resonance characteristics system LCL filter based on are analyzed, and active damping then given. On other hand, impacts modeling error stability average switching frequency...
Abstract. Rapid sulfate formation is recognized as a key characteristic of severe winter haze in China. However, air quality models tend to underestimate during heavy periods, and heterogeneous pathways have been proposed promising mechanisms reduce gaps between observation model simulation. In this study, we implemented reactive SO2 uptake mechanism through the SO2+NO2 reactions Comprehensive Air Quality Model with Extensions (CAMx) improve simulation Yangtze River Delta (YRD) region....
Abstract. Identification of various emission sources and quantification their contributions comprise an essential step in formulating scientifically sound pollution control strategies. Most previous studies have been based on traditional offline filter analysis aerosol major components (usually inorganic ions, elemental carbon – EC, organic OC, elements). In this study, source apportionment PM2.5 using a positive matrix factorization (PMF) model was conducted for urban Shanghai the Yangtze...
To meet the increasing sailing demand of Northeast Passage Arctic, a daily prediction model sea ice concentration (SIC) based on convolutional long short-term memory network (ConvLSTM) algorithm was proposed in this study. Previously, similar deep learning algorithms (such as neural networks; CNNs) were frequently used to predict monthly changes ice. verify validity model, ConvLSTM and CNNs models compared their spatiotemporal scale by calculating spatial structure similarity,...
Abstract. In recent years, ozone pollution has become one of the most severe environmental problems in China. Evidence from observations have showed increased frequency high O3 levels suburban areas Yangtze River Delta (YRD) region. To better understand formation mechanism local and investigate potential role isoprene chemistry budgets ROx (OH+HO2+RO2) radicals, synchronous volatile organic compounds (VOCs), formaldehyde (HCHO), meteorological parameters were conducted at a site YRD region...
Abstract. Elevated ground-level ozone concentrations have emerged as a major environmental issue in China. Nitrogen oxide (NOx) is key precursor to formation. Although control strategies aimed at reducing NOx emissions from conventional combustion sources are widely recognized, soil (mainly NO) due microbial processes received little attention. The impact of NO on concentration yet be evaluated. This study estimated China using the Berkeley–Dalhousie Soil Parameterization (BDSNP) algorithm....
We evaluate the one-dimensional volatility basis set (1D-VBS) and two-dimensional (2D-VBS) in simulating aging of SOA derived from toluene α-pinene against smog-chamber experiments. If we simulate first-generation products with empirical chamber fits subsequent chemistry a 1D-VBS or 2D-VBS, models mostly overestimate concentrations oxidation This is because include both aging; addition to this results double counting initial effects. treated explicitly, base-case 2D-VBS underestimates O:C...
