Measurements of atmospheric greenhouse gas (GHG) concentrations are important to assess the effect of climate change mitigation policies. Additionally, climate models depend on a precise knowledge of greenhouse gas abundances and emissions. A variety of measurement methods is addressing these needs. The Collaborative Carbon Column Observing Network (COCCON) was established in 2019, as a supporting framework for users of the portable Fourier-Transform spectrometers EM27/SUN, that measures precisely and accurately GHG column abundances from near-infrared solar absorption spectra. To ensure common quality standards across the COCCON, raw EM27/SUN measurements are processed with the PROFFAST Fortran routines. The Python interface PROFFASTpylot significantly reduces the workload during the processing of large sets of observational data and supports a network-wide consistent data processing.

For more information about PROFFAST, see Data Processing. The PROFFASTpylot source code is available at EUDAT GitLab.
