World Air Quality - OpenAQ
This dataset aggregates global air quality measurements collected by OpenAQ, a project that compiles data from government agencies and research-grade monitoring networks worldwide. In total it includes over 231 million measurements from more than 8,000 monitoring locations across 65 countries, sourced from over 100 government and research providers. It covers pollutants and air quality indicators used for environmental monitoring and public health analysis. The dataset is published through an Opendatasoft-hosted portal and is noted by the source as not currently being updated, meaning it reflects a fixed historical snapshot rather than live measurements.OpenAQ has collected 231,965,688 air quality measurements from 8,469 locations in 65 countries. Data are aggregated from 105 government level and research-grade sources. https://medium.com/@openaq/where-does-openaq-data-come-from-a5cf9f3a5c85 Note: this dataset is temporary not updated.
