BEACO2N is a new strategy for understanding green house gases (GHGs) and air quality at street level in near real time, giving pedestrians, companies, and policy-makers unique insight into their GHG emissions and air quality experiences. Instead of using a small number of highly sensitive instruments to measure GHGs and air quality, we blanket interesting locations with a network of sensors - called 'nodes' -  approximately 1 mile (2km) apart from each other. Although our individual nodes are less precise than the highly sensitive traditional sensors, when working as part of a network, our nodes create a highly detailed map of CO2 and pollutants in our air. Our nodes are sampling the air for 6 gases and also aerosol in the same locations, every minute of the day. The data provides a clear route to evaluating the effectiveness of local and regional efforts to reduce GHG emissions, improve air quality, improve environmental equity and reduce the detrimental effects of emissions on public health.

UNICORN 🦄 is now featured on the BEACO2N network map. Select ‘Heidelberg’ in the dropdown menu.
Great to have urban CO2 emission monitoring efforts connecting!

Fresh install at the Kalmit station! 🎉
Our newest node is now up and running at this key background site of the UNICORN network. Excited to see clean background data rolling in from the Palatine mountaintop. 🌄

☀️New node up in Mannheim Sandhofen Pumpwerk 🚿
It marks the furthest north node of the UNICORN network.
Thanks to the Pumpwerk team and City of Mannheim for great support!

📢 New node at the Heidelberg City Library! 📚
We’ve just installed the eighth CO₂ sensor of the UNICORN network. The city center station completes the Heidelberg network. Mannheim, we are coming 🎡
Thanks to City of Heidelberg and the library for full support!

🦄Meet the UNICORN Team: Kenneth Murai von Buenau

Kenneth is conducting his master’s thesis with UNICORN setting-up a 10m resolution transport model for Heidelberg and Mannheim to link emissions to CO2 measurements. His work will be fundamental to determine emissions from the measurements.

🦄 The UNICORN CO₂ network is growing! 🚨
Red dots = installed sensors
Blue dots = confirmed locations coming soon 🌍

We’re building an urban network in Heidelberg and Mannheim of atmospheric CO₂ - one node at a time.

Stay tuned… the first data is coming in soon! 📊✨
