Description
One of the main challenges within the climate change debate is to provide accurate climate change information at the regional to local scales, so that policy decisions on adaptation and mitigation options can be taken at the national or sub-national level. This requires the use of high resolution climate models as well as the completion of large ensembles of simulations to characterize the uncertainties in regional climate change projections. In addition, regional feedbacks due for example to landuse change and atmospheric aerosols can substantially modify the regional climate change signal, which implies the use of more comprehensive climate models than in the past. High spatial resolution, increased model complexity and need for large ensembles of simulations require a massive increase in the computational resources needed to improve the usefulness and reliability of climate change projections.
Grid infrastructures, with the large amount of computational resources available both in term of computing power and storage can provide optimal computational platforms to address this challenge. Some attempts in this direction was have been done within EU-IndiaGrid project and will be further improved in the second phase of the project where we plan to use jontly EGEE/gLite and Garuda grid infrastructure.
