Dear friends,
Happy new year and best wishes to all of you. I have ran a simulation using RegCM-4.3.5.6 for the time period 1989 - 2008. The simulation was driven by the ERA-interm and encompassed CORDEX Africa domain. When I compared the daily precipitation over some part of Africa from RegCM and others (models and observations) it is highly overestimated by RegCM4. The attached figure shows this comparison. I hope to get some direction.

Kind regards
