Information about quality is always of concern to users, whether they are buying a car or some other consumer goods, or using scientific data for research or an application. To facilitate consistent quality evaluation and description of quality information on data products for the Earth Science community, we formally introduce and define four constituents of information quality — scientific, product, stewardship and service. As requirements to ensure and improve information quality increase across government, industry and academia, there have been considerable efforts toward improving information quality during the last decade. Given this background, the Information Quality Cluster (IQC) of the Federation of Earth Science Information Partners (ESIP) has been active with membership from multiple organizations, participating voluntarily on a "best-effort" basis. This paper summarizes existing efforts on information quality with emphasis on Earth science data and outlines the current development and evaluation of relevant use cases. The IQC, with its open membership policy, is well positioned to bring together people from various disciplines and iteratively address the relevant challenges and needs of the Earth science data community. Moving forward, the IQC pledges to continue facilitating the development and implementation of data quality standards and best practices for the international Earth science community.
