Abstract
A large climate model output data archive was produced by an unprecedented coordinated effort among more than 20 climate modeling groups around the world through Coupled Model Intercomparison Project Phase 5 (CMIP5) in collaboration with Intergovernmental Panel on Climate Change (IPCC). This dataset is critical in advancing our knowledge about climate processes as well as their impacts on a number of biophysical and social dimensions. However, researchers, especially those from social science domains, often face significant obstacles to discover, access, and analyze the spatial data as it requires specialized expertise and computation resources. We have developed a climate data aggregation tool to help make the CMIP5 data easily accessible and thus more usable. Currently hosted on the GeoShare hub (https://geoshareproject.org), this tool enables a seamless workflow of selecting data of interest, downloading the data from the archive using Globus Online, aggregating the downloaded climate data to a user-specified level, and visualize the result on a map. In this presentation we will describe the design and implementation of the CMIP5 climate data tool and its impact on the user community.
