Chemistry-climate model SOCOL: a validation of the present-day climatology
International audience In this paper we document ''SOCOL'', a new chemistry-climate model, which has been ported for regular PCs and shows good wall-clock performance. An extensive validation of the model results against present-day climate obtained from observations and assimila...

International audience In this paper we document ''SOCOL'', a new chemistry-climate model, which has been ported for regular PCs and shows good wall-clock performance.

The model has a significant temperature bias only in the upper stratosphere and near the tropopause in the tropics and high latitudes.
