ENERGY-USE EMISSIONS, AIR-QUALITY, CLIMATE

• Short-lived atmospheric species (aerosols, or fine particles containing black carbon and other compounds) influence the radiation balance, atmospheric dynamics and precipitation, especially on regional scales. Their influence on ice-loss and precipitation is still uncertain.

• Our work seeks to address the scientific basis for linkages among energy-use emissions, air-quality and climate in south Asia.

• Emission scenarios are being built though a technology-based multi-pollutant emissions inventory for India, with detail to regional sectors and sources (e.g. residential cookstoves, agricultural residue burning).

• Sectoral attribution of air-quality and radiative forcing of present emissions and emission controls is under study using WRF-STEM-2K1.

• The impact of changing emissions on radiative forcing and precipitation is under study (using ECHAM5.5-HAM), along with underlying atmospheric processes and mechanisms influencing precipitation change.
