CyberConnector is a help system to bridge Earth observation (EO) datasets to the Earth scientific models (ESM). CMAQ is a famous ESM to simulate the atmosphere. This research tries to establish a cooperation example between them to demonstrate how CyberConnector can benefit the real operation of ESMs in daily work. Through CyberConnector, many other ESMs like CMAQ will have a better chance to be tested and applied with real world EO datasets. The collaboration between Cyberinfrastructure engineers and Earth scientist communities, we called a marriage, outputs a win-win for both parties and demonstrate the importance of multi-disciplinary researches in this Big Data era.
