The Philippines throughout the years have been experiencing intensified tropical storm, drought, and other extreme weather events. The objective of this module is to describe the Department of Science and Technology - Coordinated Regional Downscaling Experiment South East Asia - (DOST-CORDEX) program and its unique contribution to the understanding of climate change in the Philippines. CORDEX is a collaborative regional climate downscaling project that has been implemented under the World Climate Research Programme (WCRP) of the World Meteorological Organization (WMO) since 2012. The project involves several scientists from various countries and institutions, including the Manila Observatory. The project successfully carried out multi-model high-resolution and multi-emission scenario regional climate simulations. These data can be used by countries in the Southeast Asia region in assessing the impacts of climate change.

The first part of this module provides an overview of the program and elucidates how downscaling works. The second part gives a summary of the different projects under the program: Climate Variability (CVAR), Tropical Cyclone (TC) and Sea Surface Temperature (SST). These projects are further discussed in the succeeding modules. The latter part of this module shows the progress of the program including the workshop and conferences conducted, research  published and people trained.
