Simple Climate Models

Model Model for the Assessment of Greenhouse-gas induced Climate Change (MAGICC)
Description / Purpose Simple climate model to examine time-dependent effects. Can be used in the formulation of climate metrics for total anthropogenic sources.
Data source / Input Emissions scenarios.
Output Calculates time-dependent concentrations, radiative forcing, temperature response and sea-level rise from different perturbations.
Spatial dimension Global
Temporal dimension Annual
Sample applications Extensively used in IPCC and elsewhere.
Model Linear Climate response model (LinClim)
Description / Purpose Simple climate model to examine time-dependent effects. Can be used in the formulation of climate metrics for aviation and shipping sectors and to investigate uncertainties in climate metrics such as GTP. Can provide guidance on which technology developments are likely to result in the least environmental damage in terms of global radiative forcing and temperature response under a given scenario.
Data source / Input Aircraft fuel, shipping emissions, emission indices, reference radiative forcing from GCM, tuning parameters from GCM.
Output Calculates time-dependent radiative forcing and temperature response from different pertubations (CO2, O3/CH4(from NOx), sulphate, black carbon and contrails).
Spatial dimension Global
Temporal dimension Annual
Sample applications Used in QUANTIFY, ATTICA projects. Published results in 2 Atmospheric Environment papers in relation to aircraft application. Also used for European Commission project on developing aviation emissions trading scheme andIMOclimate impacts of shipping.
