Short summary

The Coupled Model Intercomparison Project (CMIP) is a large collaborative project to better understand the Earth’s climate system. The data produced through this project is downloaded by users around the world. In this paper, we analyze the patterns of downloads and the usage of this massive dataset. From this analysis, we make some recommendations for future data production and usage tracking.
