The Information Quality Cluster (IQC) has been active since 2014 improving understanding of various aspects of information quality and fostering collaborations nationally and internationally. During this period, NASA’s Earth Science Data System Working Groups included a Data Quality Working Group, which made several recommendations that have been documented, reviewed thoroughly and published. The IQC has had plenary and breakout sessions discussing ideas about uncertainty in Earth science datasets, which have evolved into a white paper. Significant progress has been made in defining and propagating maturity matrices for various aspects of data management including information quality. The purpose of this session is to summarize the status and accomplishments in each of these areas and discuss future directions that the IQC should take.

View Session Recording on YouTube.Session Take-Aways- Considerable progress has been made in several areas over the last 5 years. Progress reported from NASA’s Data Quality Working Group, NOAA’s Data Stewardship Maturity Matrices, OGC’s Data Quality Domain Working Group. Collaborations have developed during the last two years with connections established with other clusters and non-US/international groups including E2SIP.
- Members and observers of the IQC are looking to the IQC chairs/co-chairs for new opportunities to engage the community outside of ESIP at external conferences, namely AGU. Community engagement efforts to seek outside collaboration at IQC-organized Fall AGU sessions have been quite successful, particularly in recruiting presenters for invited talks in monthly telecons and collaborators for the uncertainty white paper.
- Progress is being made on development of a white paper on Earth science data uncertainty. IQC should consider airborne and in situ data as well - some new use cases are needed.
