Abstract. The Pearl River Delta (PRD) region in South China is faced with severe ambient tropospheric ozone (O3) pollution autumn and summer, which mostly coincides the occurrence of typhoons above Northwest Pacific. With increasingly O3 PRD under influence typhoons, it necessary to gain a comprehensive understanding impact on transport, production accumulation for efficient reduction. In this ...
The University of Western Macedonia (UoWM) has recently set up an operational system for predicting air quality in the Florina–Ptolemais–Kozani basin in Western Macedonia, Greece. This is a mountainous basin where around 65% of the total energy production of Greece takes place in lignite power plants. The concentrations of PM10 is the main air quality concern in the region, and the high particu...
[1] Regional aerosol model calculations were made using the Weather Research and Forecasting (WRF)-Community Multiscale Air Quality (CMAQ) and WRF-chem models to study spatial and temporal variations of aerosols around Beijing, China, in the summer of 2006, when the Campaigns of Air Quality Research in Beijing and Surrounding Region 2006 (CAREBeijing) intensive campaign was conducted. Model cal...
General Comment: This study pursues to outline the evaluation methods applied during the three phases of the AQMEII activity in view of building an evaluation strategy. Annual simulations of the WRF-CMAQ and IFSChimere are evaluated, as well as runs with perturbed emissions or boundary conditions or ozone deposition. The analysis focuses on ozone simulations over selected European and North Ame...
Changes in atmospheric mercury deposition are used to evaluate the effectiveness of regulations controlling emissions. This analysis can be complicated by seemingly incongruent data from different model runs, model types, and field measurements. Here we present a case study example that describes how to identify trends in regional scale mercury deposition using best-available information from m...
