This dataset contains historical air quality measurements from two major urban areas: Madrid, Spain and Cali, Colombia, obtained from api.aqi.in. The data were collected from 15 fixed monitoring stations in Madrid and 18 in Cali, offering a comprehensive view of air pollution levels in each city over time.

\n

Each record includes pollutant concentrations captured at 5-minute intervals. The pollutants and their corresponding measurement units are as follows:

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
PollutantUnit
Ozone (O3)parts per billion
Nitrogen dioxide (NO2)parts per billion
Fine particulate matter (PM2.5)microgram per cubic meter
Particulate matter (PM10)microgram per cubic meter
Carbon monoxide (CO)parts per billion
Sulfur dioxide (SO2)parts per billion
\n

 

\n

Additionally, it contains the following meteorological data:

VariableUnit
Temperaturedegrees Celsius
Dew pointdegrees Celsius
Relative humiditypercentage
\n

 

\n

Finally, each measurement contains a topic value, an integer that serves to uniquely identify the monitoring station that produced it, and the timestamp.

\n

 

\n

Data Collection and Processing:

\n
    \n
  1. Data was retrieved via the endpoint: https://api.aqi.in/api/v1/getMonitorsByCity, with the corresponding city specified in the request header.
    2. \n
  2. Records were collected at 5-minute intervals and stored in a MongoDB database in JSON format whenever new data became available.
    3. \n
  3. Non-essential fields (e.g., units, location name) were removed.
    4. \n
  4. Sensor topics were simplified by retaining only the final four digits of the topic tag.
    5. \n
  5. In Cali, 39 sensors that appeared only once were excluded to ensure data reliability.
    6. \n
\n

 

\n

Source of Data:

\n

This dataset contains air quality data originally retrieved via the api.aqi.in platform. The data is sourced from public air quality monitoring stations operated by:

\n\n

 

\n

Rights and Usage:

\n

The original data is made available through public monitoring systems by the respective municipal governments listed above. The data was accessed via api.aqi.in, which aggregates publicly available air quality information. This dataset is shared for academic and research purposes only, and to the best of our knowledge, the underlying data is in the public domain.
