Oslo CTM3 Nitrate

Equilibrium calculations with sulfate/sea salt (Myhre et al., 2006), that is, tropospheric chemistry with the applications of sulfate and sea salt. Listed here are the tracers, which are all transported (T=Y), no chemistry is involved (C=N) and all are washed out (WD=Y).

Nr Component T/C WD Remarks
61 NH3 Y/N Y Produced by emissions
62 NH4fine Y/N Y
63 NH4coarse Y/N Y
64 NO3fine Y/N Y
65 NO3coarse Y/N Y
78 H2Ofine Y/N Y
79 H2Ocoarse Y/N Y

Emissions
The nitrate module needs emissions of NH3. As for CTM2, these are taken from GEIA (Bouwman et al., 1997), where some datsets were scaled with the number of sunlit hours (Adams et al., 1999). However, any emission dataset can be used, e.g. Lamarque et al. (2010).
