The IMAGE climate model (based on [[MAGICC model|MAGICC 6.0]], [[Meinshausen et al., 2011a]]) calculates atmospheric CO<sub>2</sub> concentration based on CO<sub>2</sub> emission data for energy, industry and land-use change (Component[[Emissions]]); terrestrial carbon balance (Component [[Carbon cycle and natural vegetation]]); and carbon uptake by the oceans (calculated in MAGICC on the basis of the Bern Ocean Carbon model).

Concentrations of other long-lived greenhouse gases (CH<sub>4</sub>, N2O, and halocarbons), and tropospheric ozone (O3) precursors (CO, NMVOC) are calculated by MAGICC in a simple atmospheric chemistry module. Halocarbons and N2O concentrations mostly show a simple mass-concentration conversion and half-life behaviour. CH<sub>4</sub> and ozone dynamics are more complex, with CH<sub>4</sub> lifetime depending on the OH concentration level, and O3 and OH concentration levels depending on CH<sub>4</sub> concentrations, and NOx, CO and NMVOC emissions ([[Meinshausen et al., 2011b]]).
