The Clean Air Monitoring and Solutions Network, or CAMS-Net, is a National Science Foundation-funded project aimed at creating an international “network of networks” that will facilitate the exchange of knowledge, ideas, and data in order to improve the usage and application of low-cost sensor air quality data. The project is being led by the Columbia University Clean Air Toolbox, Carnegie Mellon University Center for Atmospheric Particle Studies, and Washington University-St. Louis, with the participation of partners around the globe.
