Atmospheric and Oceanic Science Letters16 July 2009 BC-Induced Changes in Temperature and Precipitation The deposition of absorbing black carbon (BC) aerosolon snow/ice can reduce surface albedo.A number of previous studies have examined the impacts of such BC-albedo effect on regional and global climate, but few previous studies have investigated the role of BC deposition in weather prediction.Using the chemistry version of Weather Research and Forecasting model (WRF-Chem),
