Description of Simulations

Simulation name	Description of INP treatment in model
dbfc	Dust <3 monolayers sulfate; 0.1% of biomass aerosols; standard fossil/biofuel aerosols; aircraft soot incorporated in contrails (with <3 monolayers of sulfate)
d100bfc	As in dbfc but with 100% of dust as INP
dbfa	As in dbfc but with 100% of aircraft soot as INP
dbfcs30	As in dbfc but adding 30% of SOA particles as INP
dbfc_hom	No heterogeneous nucleation in model
dbfc_dt	As in dbfc but varying the time interval for the updraft velocity
dbfc_w	As in dbfc but using a constant updraft velocity based on the local standard deviation from the parameterization
dbfc_mg10	As in dbfc but using a cutoff for moving cloud ice to snow of 400 μm instead of 250 μm
dbfSO4_mg10	As in dbfc without aircraft soot and including crystalline ammonium sulfate and using a cutoff for moving cloud ice to snow of 400 μm

Note. The default version of the cloud microphysical scheme is Morrison and Gettelman (2008; version 1.5 or mg15) if not specified in the simulation name; mg10 is version 1.0 of the scheme. SOA = secondary organic aerosol; INP = ice nuclei particle.
