The impact of manufacturing transfer in Jiangsu province, China, on the spatial-temporal variations of SO 2 emissions is investigated using estimated sector-specific SO 2 emissions, and emissions in the different transfer-in and transfer-out regions were quantified during 2000–2011. Our results show that SO 2 emissions had undergone three phases: an(More)
Data from the annual, seasonal, and hourly behavior of the criteria air pollutants CO, NO 2 , SO 2 , O 3 , and PM 10 in three Mexican metropolitan areas (the Mexico City Metropolitan Area (MCMA), Guadalajara Metropolitan Area (GMA), and Monterrey Metropolitan Area (MMA)) over the period 2000–2011 were analyzed; and compliance with Mexican air quality(More)
To understand the influence of trans-boundary air pollution on the air quality of Fukuoka, the mass concentration and chemical composition of fine particulate matter (PM) were observed at urban (Fukuoka) and rural (Fukue Island) sites in the northern Kyushu area in Japan. Chemical composition was measured using an aerosol mass spectrometer. Organic aerosol(More)
The surface area of ambient aerosols can be considered as an index of toxicity because an increased surface area may be able to act as a catalyst for specific reactions between particles and cells, as well as a carrier for co-pollutants, such as gases and chemicals. The aerosol surface area concentration was measured together with black carbon (BC) and(More)
Ozone concentrations have been increasing in the Guadalajara Metropolitan Area (GMA) in Mexico. To help devise efficient mitigation measures, we investigated the ozone formation regime by a chemical transport model (CTM) system WRF-CMAQ. The CTM system was validated by field measurement data of ground-level volatile organic compounds (VOC) and vertical(More)
Fog is a meteorological/environmental phenomenon which happens across the Indo-Gangetic Plains (IGP) and leads to significant social and economic problems, especially posing significant threats to public health and causing disruptions in air and road traffic. Meteorological stations in Pakistan provide limited information regarding fog episodes as these(More)
The Japan Oceanographic Data Center has been submitting oceanographic data to the World Data Center)for oceanography through the framework of the International Oceanographic Data and Information Exchange committee sponsored by the UNESCO/IOC. In the World Ocean Database 2009 which is the compiled database of WDC for oceanography, the Japanese contribution(More)
