SEACLID/CORDEX Southeast Asia: A Regional Initiative to Provide Regional Climate Change Information and Capacity Building Liew Ju Neng SEACLID/CORDEX Southeast Asia School of Environment and Natural Sciences Faculty of Science and Technology National University of Malaysia 14 Countries, 18 Institutions involved in the project (http://www.ukm.edu.my/seaclid-cordex) Workshop for Capacity Building on Climate Change Impact Assessments and Adaptation Planning in the Asia-Pacific Region, 27-28 January 2016, Manila.
Projected Mean Surface Temperature & Mean Precipitation by end of 21 st Century The temperature increase during the last 100 years was about 0.8 o C. IPCC AR5 Synthesis Report
Background Local climate projection facilitate local CC impact assessment. Global > Local scale cascading of modeling processes. Uncertainties are introduce at each modeling levels. Run multiple downscaling simulations and create ensemble with uncertainty ranges.

Southeast Asia Regional Climate Downscaling (SEACLID) Initial Member Countries: Malaysia, Indonesia, Vietnam, Philippines, Thailand First Workshop hosted by VNU Hanoi University of Science, Vietnam, 2-3 Aug 2012
SEACLID/CORDEX SEA objectives Create a platform for scientists (especially young scientists) within and outside the SEA region to collaborate on issues related to regional climate downscaling; On a task-sharing basis, carry out a joint regional climate downscaling activity over a common SEA domain with RegCM4 (and other RCMs) using a number of CMIP5 GCMs and RCP scenarios; Collectively analyze model performances, create an ensemble of regional climate projection scenarios for the SEA region, and establish a web portal and data center for efficient data dissemination (ESGF); Narrow knowledge gaps related to regional climate change in SEA by increasing peer-review scientific and policy-relevant publications and strengthen research capacity and capability, particularly in numerical regional climate modeling.
