Automatic Greenhouse Gas Monitoring System in Central Munich

We have recently established the worldwirde first regional greenhouse gas sensor network based on differential column measurements. The Munich network consists of five fully-automated and highly precise FTIR monitoring systems using the sun as light source, distributed in and around the city. It allows us to measure CO2, CH4, CO and NO2 column concentrations and quantify the emission trend throughout the years. More information about the network can be found in here.

All stations are equipped with an FTIR spectrometer that is placed in our own developed patented automated weather-resistant housing. Its cover follows the movement of the sun and closes when it starts to rain to protect the optical and electronic components inside. Whenever it is sunny, the cover opens automatically and the system starts to measure. Our measurements started in August 2015.
