The Total Carbon Column Observing Network (TCCON) is a network of ground-based Fourier Transform Spectrometers that record direct solar absorption spectra of the atmosphere in the near-infrared. From these spectra, accurate and precise column-averaged abundances of atmospheric constituents including CO2, CH4, N2O, HF, CO, H2O, and HDO, are retrieved. The TCCON GGG2020 Data Version is produced using the algorithm as described in the preprint 'The Total Carbon Column Observing Network's GGG2020 Data Version'.
