Angular — Air quality at three stations of the RER (parisian railway)

Updated on 2023-10-22

The RATP provides open data on air quality at various RER (Regional Express Network) and metro stations through its Open Data RATP website.

I have developed an application that allows users to view all data on air quality (temperature, relative humidity, carbon dioxide, nitrogen oxides, particles) in three stations of the RER A line (Auber, Châtelet, Nation). The application is built using the Angular 16 framework, PrimeNG library for the graphical components and Plotly for visualizing data.

This project is not affiliated with RATP Group.

Demo & Source Code

A demo of the application is available online here: https://jldblog.github.io/rer-air-quality.

The application's source code is licensed under the GNU GPLv3 and is available on GitHub at https://github.com/jldblog/rer-air-quality.

Data

The weekly dataset includes average hourly values for all the stations:

• Ambient temperature in degrees Celsius (°C)
• Relative humidity in percent (%RH)

And according to the stations:

• CO2 in ppm (Auber)
• NO in μg/m3 (Auber)
• NO2 in μg/m3 (Auber)
• PM10 in μg/m3 (Auber, Châtelet and Nation)
• PM2.5 in μg/m3 (Auber and Nation)
