Abstract Carbonaceous aerosol emissions from biomass fuel combustion in cooking stove is an important and less understood contributor to climate forcing over South Asian region. Also the contribution of brown carbon (BrC) from this source is unresolved and need utmost importance to understand climate change. The global simulations suggest that the strongly absorbing BrC contributes up to +0.25 W m−2 or 19% of the absorption by anthropogenic aerosols. Emissions from biomass burning are a significant source of brown carbon (BrC) in the atmosphere. On field studies on emission of OC, EC and BrC from biomass fuel combustion in cookstoves are particularly limited in key regions like India, where over 80% of residential energy requirement meet through these fuels. In this study, we present the mass emission factor of OC, EC, and BrC from on-field measurement of fine aerosol during meal preparation in villages of North India. The emission measurement was conducted during regular cooking of the household using biomass fuel as a source of cooking energy. Fine aerosol samples were collected on quartz filters with the help of a multistream sampler equipped with cyclone saperator designed for cutoff diameter 2.5 μm at 10 lpm flow rate. The filters were subjected for OC, EC and Brc analysis using standard protocols. This study, will present the emission factor of carbonaceous aerosol and brown carbon and will discuss its climate implications.
