The Inter-Continental Transferability Study as part of CEOP/GEWEX 1
Objectives Study the transferability of regional climate models to areas of different climate regimes (RHP domains) Apply CEOP data (satellite, reference sites, global analysis) to evaluate the regional climate models 2

Outlook - ICTS in CEOP 2 Further analysis of? Simulations performed in CEOP1 Simulations with higher resolution forcing by different global analyses for areas where differences between global analyses are significant enhanced simulation period (beyond i.e. for CEOP2, 10 years) additional MOLTS additional domain (NEESPI) revision of output parameter list update with new model versions
