A study of aerosol optical depth (AOD) using MICROTOP-II
Sunphotometer has been carried out at three different places over
Delhi (tropical semi-arid climate) viz. Jawaharlal Nehru University
(JNU), Mukherjee Nagar (MN) and Patel Nagar (PN). Results show a
systematic spectral dependence of AOD according to classical Mie
scattering theory. To characterize AOD, Angstrom parameters and
have been analyzed and results show an inverse relationship between
them over all the sites. Aerosol size distribution has been
determined from AOD measurements using King et al. (1978) inversion
algorithm. Daily mean columnar aerosol size distribution shows
power law size distribution i.e. Junge size distribution. Diurnal
variations of AOD and that have been studied over JNU only indicate
vehicular emissions as a main source of aerosol loading. The Coarse
Mode Fraction (CMF) and Fine Mode Fraction (FMF) results of all the
sites show the dominance of fine aerosol particles further
strengthening the result that vehicular emissions are the major
source of air pollution over Delhi."
