Multi-year objective analyses (OA) on a high spatiotemporal resolution for the warm season period (1 May to 31 October) for ground-level ozone and for fine particulate matter (diameter less than 2.5 microns (PM2.5)) are presented. The OA used in this study combines model outputs from the Canadian air quality forecast suite with US and Canadian observations from various air quality surface monit...

Surface ozone (Surface O3)is a secondary pollutant and there are only limited studies on ozone in South India. Studies have revealed a strong correlation between higher ozone levels and warmer days. Surface O3 along with its precursors like NO2, CO and CH4 are being measured at Kanyakumari (8.0780° N, 77.5410° E), TamilNadu, India and in this paper we present the summer time variation of ozone ...

Air quality data (ground level ozone (O3), NO, NOx, SO2, CO, H2S and NH3) of two Kuwaiti urban areas adjacent to petroleum processing facilities, Fahaheel and Al-Riqa, were analyzed and compared to evaluate: (1) the exceedances of the Kuwait Environment Public Authority (KUEPA) air quality limits, (2) primary air pollution sources and their contribution to the ambient load, (3) diurnal patterns...
