Our team will carry out the required modifications to an existing model and develop a better model for the Indian region through improved physical and computational implementations. Specifically, we will develop the ICCM through process improvements and region-specific customization that will satisfactorily simulate the regional climate of India. Our model will be used for future climate projections at district level to assess the impacts of climate change on agriculture, health, water resources, and the energy sectors. Furthermore, we will downscale the ICCM outputs at ultra-high resolutions for various applications. Additional climate projections for the future scenarios will be made by combining the ICCM projections with soft computing, machine learning, and mathematical optimization techniques. In addition to the research objectives, our CoE will play a leading role in training and nurturing future climate modelers of India in order to sustain and augment this key component of climate science.
