| Zusammenfassung |
| Five portable Bruker EM27/SUN FTIR (Fourier transform infrared)
spectrometers have been used for the accurate and precise observation of
column-averaged abundances of CO2 and CH4 around the major city
Berlin. In the work by Frey et al. (2015), a calibration procedure is
developed and applied to the set of spectrometers used for the Berlin
campaign. Here, we describe the observational setup of the campaign and
aspects of the data analysis, and we present the recorded time series of
XCH4 and XCO2. We demonstrate that the CO2 emissions of
Berlin can be clearly identified in the observations. A simple dispersion
model is applied which indicates a total strength of the Berlin source of
about 0.8 t CO2 s−1.
In the Supplement of this
work, we provide the measured data set and auxiliary data. We hope that the
model community will exploit this unique data set for state-of-the art
inversion studies of CO2 and CH4 sources in the Berlin area. |
