AB  - Munich's low-cost sensor network SCOUT (Street-level Carbon Observatory for Urban Territory) comprises 100 Decentlab DL-LP8 devices. They include a temperature, humidity, and barometric pressure sensor to complement the CO2 measurements. The sensors are strategically positioned at locations with different emission characteristics and partly co-located with air quality sensors, traffic detectors, and more precise CO2 sensors to assess data correlations and quality. An accuracy improvement of factor 5 to 10 compared to the manufacturer’s accuracy was achieved with our bias correction algorithm and individually trained sensor models. Additionally, we upgraded the systems with solar radiation shields to mitigate radiative heating effects and reduce temperature-induced sensor errors.
