Abstract:
The characteristics of aerosol black carbon (BC) were studied at two different climatic
regimes, i.e. Delhi and Manora Peak during winter and spring of 2007. Spring BC was found
to be ∼59% lower at Delhi and ∼23% higher at Manora Peak than their corresponding
winter BC. Diurnal BC variation showed two enhanced peaks at Delhi (morning and night)
whereas a single late afternoon peak at Manora Peak. Delhi BC showed a clear correlation
with prevailing winds whereas no correlation was observed at Manora Peak. The major
contribution of BC at Manora Peak can be expected from biomass burning while at Delhi
fossil fuel dominates. Copyright ©2012 Royal Meteorological Society.
