ICOS Cities – Mid- and low-cost CO2 measurements

The ICOS Cities project is a project for emission monitoring, utilizing various sensors including Decentlab's DL-LP8P and DL-ATM22. The CO2 sensor network in Zurich has been operational since mid-July 2022, with 21 mid-cost sensor locations installed throughout the city. The captured data has allowed the research team to continuously determine emission flux ratios and monitor changes over time and with different wind directions.

During an episode between October 28 and 31, the network experienced its highest concentrations due to cooler temperatures and a lack of wind. As of the beginning of January 2023, on-site wind observations are now available at 20 of the 21 mid-cost sensor locations.

Zurich is collaborating with teams in Munich and Paris for data and knowledge transfer, with the three sensor teams working on an interim data specification to facilitate easy data sharing among users before the end of the year.
