AIRTHINGS : Open Data Platform

Jan 13, 2020

The data from the 22 sensor stations for air quality in Sofia can be monitored in real time from today via Open Data Platform at:

The 22 sensor stations installed by Sofia Municipality and the Open Data Platform are part of the activities under the AIRTHINGS project funded by the European Union under the Balkan - Mediterranean Program (2014-2020). Sofia Municipality is a leading partner in it together with four other cities - Thessaloniki, Nicosia, Tirana and Skopje. Within the project, all partners will install a total of 91 air quality sensor stations.

The stations are a set of monitoring sensors which measure major pollutants such as PM10, PM2.5, nitrogen dioxide, sulfur dioxide, ozone, carbon monoxide, and meteorological parameters such as temperature, humidity and pressure. The sensor stations allow future upgrades with additional sensors (for example, noise pollution).

Real-time station measurements are transferred to a cloud platform for storage, visualization and further analysis. Everyone can check the current station readings and the status of various pollutants, as well as the history of the readings from the last 14 days. The air quality around the station is easily perceived through an air quality index.

Following the Open Data System standards, the platform also provides data in an open, machine-readable format. The system improves its accuracy by storing more data. For proper assessment it is necessary to go through at least 4 seasons in order to analyze the seasonality of the data, i.e. how climate change across seasons affects data quality and measurements.

The air quality data of all project partners will be displayed on the same platform which will create network of connected cities for joint air monitoring in the region using innovative technologies.
