Our results show that particle mass production in an outflow plume is a robust feature of our model. The production is largely insensitive to reasonable variations in the seed

Measurements of aerosol chemical composition and aerosol optical depth in the Nepal Himalaya have clearly shown the build up of aerosols in the pre-monsoon season during the winter
