With the strict emission control measures implemented in China and India, reductions in emission would lead to appreciable benefits of air quality and public health. However, such air quality-driven and sector-based measures did not consider climate effects, which is likely to accelerate global warming. The Weather Research and Forecasting Model coupled with Chemistry (WRF-Chem) is used to investigate the direct radiative forcing induced by aerosols from emitting sectors in China and India in 2013. The direct radiative forcing induced by aerosols from all sectors at the top of the atmosphere (TOA) is -2.21W/m2 in China and-3.18W/m2 in India, which are mainly contributed by the power sector. As the main contributor to black carbon emissions, the residential sector dominates atmospheric warming in both China and India. The shortwave radiative forcing is -3.07 and-4.39W/m2 in China and India, which is larger than longwave radiative forcing of 0.86 and 1.21W/m2, respectively. These results suggest that control of emissions from the residential sector would be beneficial to air quality, climate and human health; however, the measures in power sector may oppositely affect climate.
