AB: Observations of aerosol properties in the Southern Indian Ocean region during the Indian Ocean Experiment (INDOEX) of 1999 have provided evidence that continental emissions from South Asia may be modifying climate patterns in the region. During the INDOEX intensive period of January-March 1999 the predominantly northeasterly winds associated with the winter monsoon carried continental emissions of anthropogenic aerosols and their precursors to pristine areas in the Southern Indian Ocean. Model applications with METCHEM, a coupled meteorology-chemistry model driven by recently compiled fine-resolution (0.25 deg x 0.25 deg) emissions data over all of India, examine the effects of these emissions on the aerosol radiative feedbacks to climate variables over the region. Preliminary results of aerosol properties and radiative effects are presented and compared with available INDOEX surface and shipboard measurements from the January-March 1999 intensive period.
