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 GGG2020 data release of observations from the TCCON station at California Institute of Technology, Pasadena, California, USA.","keywords":"TCCON, Greenhouse gases, carbon dioxide, methane,
