The impacts of improved atmospheric absorption on radiative fluxes, atmospheric circulation, and hydrological cycle for long-term GCM integrations are investigated. For these runs the operational version of the Centro de Previsão de Tempo e Estudos Climáticos (CPTEC) AGCM and its enhanced version wi...
