Short summary
We tag BC emissions from 13 source regions around the globe in a global chemical transport model MOZART-4 and optimize the aging timescale for each source region by minimizing errors in vertical profiles of BC mass mixing ratios between simulations and HIAPER Polo-to-Pole Observations (HIPPO). We find that the optimized aging timescale of BC varies significantly by region and season. Our simulations indicate that BC lifetime increases nearly linearly with aging timescale for all source regions.
