Regional climate modelling groups from throughout the region collaborated to compare their models. This set the scene for comparing regional projections of the future climate by these models, a process that will provide vital information for policy-makers. Information from this project is feeding into the Assessment Reports of the Intergovernmental Panel on Climate Change (IPCC). APN funding helped networking between RCM research groups in Asia through workshops and joint research, and also supported capacity building in developing countries through training courses and fellowships.
