In this way, a modified version of the Global Resolved Energy Balance (GREB) climate model was developed, making it possible to simulate new scenarios. The new model is being called GREB-GCR. The results suggest that the joint action of GCR and CO2, Experiment 20 (EXP20), presented a better representation on the surface temperature when compared to the exclusive action of CO2, Experiment 12 (EXP12). This fact is mainly evidenced on the oceans. It was identified from the root mean square error (REQM) that the EXP20 presented a spatially reduction of the error on the tropical region while compared to the EXP12. However, it is noteworthy that in both experiments the GREB-GCR model presented more significant errors on high altitude and polar regionsAttribution 3.0 Brazilhttp://creativecommons.org/licenses/by/3.0/br/Simulação Raios Cósmicos GalácticosGalácticosClimaarticle10.26848/rbgf.v12.3.p768-778
