CORDEXA COordinated Regional climate Downscaling EXperiment
WCRP formed a task Force on RCD aiming to bring togetherefforts in GCM and RCD communities in order to betterunderstand climate change:
(i) framework to evaluate and improve RCD techniques foruse in downscaling global climate projections
(ii) multi-model RCD-based high resolution climate changeinformation for impact/adaptation work and IPCC AR5
(iii) interaction and communication between global climatemodelers, the downscaling community and end-users tobetter support impact/adaptation activities

Summary and perspectives
• climate change on the long time scale we should headingtowards ice age, but instruments shows warming up to 1.5K since last 50 years
• evaluation run known problems (cold bias up to 1K inannual mean, and wet bias in monthly summ from 40mm/month
• historical run preliminary results (cold bias up to 2K inannual mean, wet bias up to 50 mm/month ), but itcaptures trend of climate change in historical period
