Abstract

Regional climate model REMOTE is employed to assess the impact of two new sources of marine aerosol precursor vapours (DMS and volatile organo-iodine vapours) on the aerosol population. Microphysical model M7 is applied within REMOTE to simulate gas to particle conversion processes. Results indicate new ultra-fine particle production of the order of 103 particles cm^-3 in the North East Atlantic, predominantly due to the nucleation of iodinecontaining vapours. The consideration of DMS vapours in the model leads to an increase in sulphur gases (factor of 1.5-2) which is of sufficient magnitude to enhance the growth of accumulation mode particles over the model domain, the resulting effect on the radiative properties of the atmosphere of potential global significance.
