Overview

Each dry-depositing GEOS-Chem species has one or more of the following properties defined, depending on whether it is an aerosol or gas:

Properties for aerosol species

Quantity Units Description
DD_AeroDryDep 1 For sea salt species, set this to TRUE. This will use dry deposition routine AERO_SFCRSII to perform aerodynamic dry deposition accounting for hygroscopic growth.
DD_DustDryDep 1 For mineral dust species, set this to TRUE. This will use dry deposition routine DUST_SFCRSII to perform aerodynamic dry deposition omitting hygroscopic growth.
DD_DvzAerSnow cm/s For certain aerosol species, DD_DvzAerSnow specifies the dry deposition velocity over ice and snow. This usually 0.03 cm/s.
DD_DvzMinVal cm/s A 2-element vector that specifies the minimum dry deposition velocity for sulfate species SO2, SO4, MSA, NH3, NH4, NIT. This follows the methodology of the GOCART model).
  • DD_DvzMinVal(1): Specifies minimum drydep velocity over snow/ice
  • DD_DvzMinVal(2): Specifies minimum drydep velocity over land

Properties for gas-phase species

Quantity Units Description
DD_Hstar M atm-1 This is the Henry's law solubility constant (for T = 298.15 K and pH = 7) that is used in the GEOS-Chem dry deposition module. We use pH = 7 because this is the pH value of plant stomata.

NOTE: the DD_Hstar value as used in the GEOS-Chem dry deposition module is tuned to produce the correct depositon velocity. So that is why species can have different values for DD_Hstar and Henry_K0.

DD_F0 1 Reactivity factor for oxidation of biological substances
DD_KOA 1 Octanol-air partition coefficient, used for the POPG tracer in Persistant Organic Pollutant (POPs) specialty simulations.
