About
Aggregating over 230 million air quality measurements, this collection offers a substantial repository of atmospheric data sourced from 8,469 locations across 65 countries. The data is consolidated from 105 government-level and research-grade sources, providing a global perspective on environmental conditions. It is important to note that owing to the raw nature of the API data, some records may contain encoding issues on specific characters, and certain entries may display dates set in the future; these anomalies have not been corrected in the dataset.
