The second phase of the SEACLID/CORDEX Southeast Asia project will examine climate extreme events over key areas within Southeast Asia through active engagement and collaboration with stakeholders/end-user groups. Key vulnerable areas in the region will be identified (e.g. megacities, coastal/low-lying urban, areas of frequent flooding or drought) based on their exposure and vulnerability to climate extremes and will be further refined through consultation with stakeholders/end-user group at the beginning of the project. Further downscaling over these key vulnerable areas will be carried out using the multi-model and multi-scenarios using inputs from data generated from the first phase of the project, to generate high-resolution (3 km) climate projection data. This newly generated dataset will be archived as part of the Earth System Grid Federation (ESGF) that allows free access to user community. Model performances, biases and projection uncertainties will be examined and data usage guidelines incorporating this information will be developed and disseminated to users at the end of the project. This project will not only strongly support APN’s research agendas on climate change and variability, and risk reduction and resilience at regional scale but also have direct relevance to international processes such as the IPCC, UNFCCC and IPBES.
