Variations in mass concentrations of airborne particulate matter over tropical urban environment

0

Particulate matter (PM) is an important component of the air pollution that has adverse health effects, ecosystem damage and degraded visibility. We analysed the seasonal variations in PM loading from ground-based measurements of PM1.0 and PM2.5, Aerosol Optical Depth (AOD) Black Carbon (BC) aerosol over Hyderabad, India during January-June, 2006. The PM concentrations showed relatively higher values during winter period and lower values during summer. PM1.0 values showed positive correlation with BC, OMI-AI, MODIS-AOD and ground measured AOD. The seasonal variations in PM1.0 were attributed to vehicular traffic patterns, biomass burning and dust aerosols over the region.
