Data sources

The data in this platform are from low- and medium-cost sensors (defined here as sensors that typically cost between $20 and $25,000) that have been deployed by a variety of stakeholders, including citizen scientists and community advocates, expert researchers, government agencies, sensor manufacturers and others. Anyone can upload data onto AQDC as long as the data are compatible with AQDC's basic quality characterizations (e.g., the data use AQDC's Date and Timestamp Guidelines and include meteorological data). AQDC makes no guarantees about the quality, accuracy, and/or precision of the data uploaded by data providers.
