Overview of ICARUS-A Curated, Open Access, Online Repository for Atmospheric Simulation Chamber Data

Area of Science:

• Atmospheric chemistry and physics
• Environmental science
• Data science

Background:

• Atmospheric simulation chambers are crucial for atmospheric science research, informing chemical transport models used in policy decisions.
• A lack of centralized data management and access for chamber study products has hindered progress.
• Existing data infrastructures do not adequately serve the specific needs of atmospheric chamber research.

Purpose of the Study:

• To introduce ICARUS (Integrated Chamber Atmospheric data Repository for Unified Science), a novel open-access infrastructure for atmospheric chamber data.
• To provide a centralized platform for storing, sharing, discovering, and utilizing scientific data from atmospheric chambers.
• To facilitate data accessibility and interoperability for researchers, modelers, and educators.

Main Methods:

• Development of a web-based infrastructure with distinct data intake and search/discovery portals.
• Implementation of data curation, standardization, and metadata enrichment, including vocabulary control and version tracking.
• Integration with external databases like PubChem for chemical entity management and enabling targeted data discovery based on experimental parameters.

Main Results:

• ICARUS offers a searchable repository of curated, uniform, and citable atmospheric chamber data.
• The platform supports discovery based on detailed experimental parameters (e.g., reactants, oxidants, NOx, RO2 fate, seed particles, conditions).
• Data are indexed on search engines, mirrored by other repositories, and comply with open access mandates.

Conclusions:

• ICARUS addresses the critical need for centralized atmospheric chamber data management and access in the US and globally.
• The repository enhances the evaluation, revision, and development of atmospheric models, leading to improved predictive capabilities.
• Open access and interactive data in ICARUS support broader applications, including teaching, data mining, and machine learning model training.
