Munich Campaign: Joint National and International Effort for Assessing Greenhouse Gases and NOx Emissions


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 2050.

In September and October 2017, an international joint campaign led by Prof. Chen and her group has been carried out, to determine the greenhouse gas and NOx emissions in Munich. The partners include Harvard, DLR, KIT, and LMU. The team deployed 6 solar-tracking Fourier transform spectrometers in and around Munich for measuring CO2, CH4 and CO, and 2 MAX-DOAS for measuring NOx.

This campaign is a follow-up of a series of city investigations carried out in US, including Indianapolis and San Francisco Bay Area (PI: Prof. Wofsy, Harvard). We brought 2-3 spectrometers to US to joinly measure CO2 and CH4 emissions with our Harvard, Caltech, LANL, and Berkeley colleagues.
