Atmospheric Voigt Line List for the TCCON 2020 Data Release

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. This is the atmospheric line list for lines with Voigt lineshapes for the TCCON GGG2020 data release. The R1 version adds 3 additional linelists used by GGG2020.
