Oslo CTM3 Aerosols

The Oslo CTM3 comprises several aerosol parametrizations. They are listed here, while more details can be found in the aerosol section in the menu to the left. For an overall reference to the various aerosols modules as well as optical and radiative properties and comparisons to observations, see Myhre et al. (2009).

Note that some of the aerosol modules are so far only available in the Oslo CTM2.

Sulfate
Sulfate is calculated using the sulfur chemistry scheme, and applies for the troposphere only. More details on the sulfur module in the chemistry section in the menu to the left.

Black Carbon / Organic Carbon
A stand-alone part of the model, using 8 tracers. A simple set-up with emissions, transport, wet and dry deposition and conversion from hydrophobic to hydrophilic aerosols. More details on the BCOC module in the BC/OC section in the menu to the left.

A module for secondary organic aerosols (SOA) is available for Oslo CTM2, and will in due time be implemented in CTM3 also. See the other aerosols section in the menu for more.

Sea salt
A stand-alone module, with emissions are driven by the model winds. More details on the salt module in the sea salt section.

Mineral dust
A stand-alone module, with emissions are driven by the model winds. More details on the dust module in the mineral dust section.

Nitrate
A module for fine and coarse mode nitrate aerosols. The fine mode nitrate is linked to the sulfate module, and hence requires tropospheric chemistry also. More details on the dust module in the nitrate section.

M7
M7 is a module for coupling together different aerosol packages. It is available only for Oslo CTM2 for now, see the other aerosols section in the menu for more.
