Questions:1.Should blowing snow emissions to be turned on by default? 2.Should we separate the blowing snow and open ocean emissions (currently they are lumped in together in HEMCO)
Brown Carbon from Fires
● Fires are the largest source of BrC; BrC dominates uncertainty in the sign and magnitude of DRE of fires
● Considerable uncertainty in initial absorption from different fires and how this evolves in the atmosphere (field observations generally consistent with a ~1 day photochemical bleaching)
● Could be added to standard simulation (requires addition of 3 tracers) if sufficient interest
