| Abstract: | Ventilation coefficient (VC) over urban area
of Hyderabad, India during night-time in 2008 has
been calculated using night-time mixed layer height with boundary layer lidar
(BLL) and radiosonde data to investigate the influence of VC on pollutant concentration.
Carbon monoxide (CO), ozone (O3) and black carbon (BC) aerosol mass
concentrations in relation to mixed layer height and wind speed have been
analysed for different seasons, viz. winter, pre-monsoon, monsoon and
post-monsoon associated with boundary layer and ventilation coefficient (VC).
The results of the study suggested that VC plays an important role in
dispersing the pollutants. |
