Transport
Advective transport is done using the highly accurate and low-diffusive Second Order Moments (SOM) scheme (Prather, 1986). Whereas the Oslo CTM2 uses the 1986-version of SOM, the Oslo CTM3 is updated to the 2006-version (Prather et al., 2008).
The parameterization of deep convection is based on the Tiedke mass flux scheme (Tiedke, 1989), while boundary layer mixing is treated according to the Holtslag K-profile scheme (Holtslag et al., 1990).
Transport is driven by meteorological data, which in principle can be retrieved from any numerical weather prediction model or general circulation model. Currently we use data from ECMWF, and you find more about the meteorological data in the menu to the left.
