The publication covers the first study worldwide that determines the methane emission of a big festival. We found that such festivals are significant sources of the potent greenhouse gas methane. However, they are not considered in the state-of-the-art emission inventories so far.... [mehr]

Our paper "Spatial and temporal representativeness of point measurements for nitrogen dioxide pollution levels in cities" is published in ACPD: https://www.atmos-chem-phys-discuss.net/acp-2019-1198/ [mehr]

Our worldwide unique greenhouse gas network has been launched. The network consists of five fully-automated and highly precise FTIR monitoring systems using the sun as light source. It allow us to measure CO2, CH4, CO and NO2 column concentrations throughout the year. The five... [mehr]

In the ZEIT Wissen magazine 5/18 you can find an interesting interview with Prof. Chen about the research of our group and the air quality in cities: https://www.zeit.de/zeit-wissen/2018/05/klima-wetter-luft-himmel-klimawandel-umwelt (so far you have to register for free first... [mehr]

Our paper on our automated sensor system for greenhouse gas monitoring in Munich is published on AMT: https://www.atmos-meas-tech.net/11/2173/2018/amt-11-2173-2018.html [mehr]

Prof. Chen and our research are featured in  "Faszination Forschung - 150 Jahre TUM": Abstract: "Jia Chen is trying to track greenhouse gas emissions such as carbon dioxide and methane. The 36-year-old scientist has developed optical sensing and modeling methods that allow... [mehr]

The majority of anthropogenic greenhouse gas emissions originates from cities, therefore monitoring emissions in cities is essential to fight climate change. Munich sets up an ambitious emission reduction goal to cut CO2 emissions by 10% every 5 years and be carbon neutral by... [mehr]


We joined the San Francisco Bay area campaign with Harvard, UC Berkeley, Caltech, KIT and DLR, we brought 3 EM27SUN from Germany to carry out the greenhouse measurement in SF [mehr]
