As a part of the ICOS Cities project, 13 high precision instruments have been installed on mobile antenna towers within the City of Zurich, one of the three pilot cities in the project.
In collaboration with Swisscom, instruments measuring CO2 concentrations has also been installed on their high tower mobile antenna.
"The network of 13 high precision instruments on rooftops is complemented with approximately 60 low-cost sensors, installed for example on lamp posts. All measurements are then combined in models to estimate CO2 emissions and monitor implemented measures for emission reduction," says ICOS Cities Scientist Pascal Rubli.
Zurich aims to be climate-neutral by 2040 and joined the ICOS Cities project in 2020, with the aim of developing systematic observations to monitor the level of greenhouse gas emissions in urban areas. Researchers from 15 countries are collaborating in the project setting up a CO2 monitoring network. In total, there are three pilot cities in the project: Zurich, Paris and Munich, and also 12 other European cities are involved in the city network.
