Abstract: | Aerosol particle size distribution and chemical properties are important in studies related to human health and climate. The
present study describes an analysis of aerosol mass loading, Aerosol Optical Depth (AOD), black carbon aerosol mass concentration
and carbon monoxide over tropical urban region of Hyderabad, India, during March 2006, coinciding with active forest fires
season over India. Aerosol optical depth, particulate matter mass loading and carbon monoxide were observed to be high on
days with air mass coming from north of the study area.
Spatial occurrence of forest fires was analysed using MODIS daytime data and DMSP-OLS nighttime data sets. Aerosol optical
depth measured using Microtops-II sunphotometer correlated well with MODIS derived AOD values. Results of the study suggested
that synoptic meteorological conditions play an important role in the observed aerosol properties over the study area during
the forest fire season. |
