To determine that Regional Climate Models can realistically simulate the climate variability in all regions of the globe, we want to develop parameterizations that are evaluated against observations in all possible climates.
Regional atmospheric climate Models from different Continental Scale Experiments (CSE) were transferred from their “native domain” to other continents involved in the Inter-CSE Transferability Study (ICTS) - GEWEX project.
The ICTS Regional Climate Modeling protocol aims to capitalise on the global coverage offered by CEOP observations
to assess and improve the global transferability of RCMs
Unmodified RCMs were run on a variety of domains around the globe
