Measurements of carbonaceous aerosols at urban and remote marine sites

Concentrations of total carbon (TC) and black carbon (BC) in ambient air at Delhi (urban site) and over Indian Ocean (remote marine) were determined as a part of INDOEX programme. Over Indian Ocean, the TC and BC concentrations varied from 1.81 to 10.05 μg/m3 and 0.13 to 1.36 μg/m3 respectively during FFP-98. During the same season at Delhi, the TC and BC ranged from 7.50 to 40.27 μg/m3 and 0.49 to 2.84 μg/m3 respectively. In addition, at Delhi, the TC and BC concentrations were noticed very low during the monsoon season. However, the percentage BC during monsoon season was very high compared to winter season. High concentrations of TC were observed due to high organic carbon (OC) which might be due to biomass burning of various kinds. Similar to Delhi, near Indian coast, the concentration of OC was very high while towards ITCZ and across ITCZ, OC content was relatively lower

In Situ Airborne Measurements of Aerosol Optical Properties During Photochemical Pollution Events

Aerosol optical properties (scattering, absorbing coefficients and single scattering albedo) were derived from in-situ aircraft based measurements during two photochemical pollution events near Marseille. Both horizontal distribution and vertical profiles are presented. Plumes of enhanced scattering and absorption are observed to be formed in the sea-breeze-driven outflow of the coastal urban-industrial area of Marseille. Simultaneously, the domain-averaged absorption coefficient increases significantly. Differences in photochemical activity lead to different single scattering albedo. The changes in optical properties happen almost entirely within the boundary layer. No significant variation of optical properties are observed in the Upper Layer (1 - 3 km), where the aerosol optical properties are considered to be well mixed.JRC.H.2-Climate chang
