Abstract<br><br>Citizen science benefits society by involving the general public in scientific research to help solve problems. However, existing software and data are ad-hoc, disjointed, non-interoperable, non-standardized, and isolated – resulting in citizen science software and data siloes. This project will develop an integrated cyber-infrastructure to transform the current scenario of isolated data and software into a sustainable network of interoperable systems. Such integration and interoperability will improve the discovery, appraisal, collection, exploration, visualization, analysis, reanalysis, use, and reuse of citizen science software and data across multiple disciplines and scales to solve diverse human and ecological challenges.<br
