Abstract:
In August 2018, we deployed five solar-tracking Fourier transform spectrometers (EM27/SUN) in the urban area of Munich to measure the column-averaged dry-air mole fraction of the three gases carbon dioxide (CO2), methane (CH4), and carbon monoxide (CO). The setup is characterized by a central station and a station in each compass direction, spaced about 20 km apart, to measure the inflow and outflow of the gas concentrations under any wind conditions. With this setup, it is possible to determine urban greenhouse gas emissions when an appropriate atmospheric model is applied to these concentration data in conjunction with additional meteorological parameters such as wind.

Comment:
To obtain these data, solar interferograms were captured with the solar-tracking Forier transform spectrometer EM27/SUN during a one-month measurement campaign in Munich, Germany. To obtain the column-averaged dry-air mole fractions of the gases of interest, the GGG2014 algorithm (Wunch et al., 2015) was used, which is also used to retrieve all TCCON data. The standard TCCON parameters were applied, including the airmass-independent correction factors. The spectral windows for retrieving different gas species were slightly modified according to the EGI setup.
