TCCON data before QAQC from Paris (FR) , Release GGG2020.R0

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 GGG2020 data release, before QAQC by the TCCON network, of observations from the TCCON station at LERMA, Sorbonne Université, Campus Pierre et Marie Curie, 4 Place Jussieu, Paris 05, France. Data are updated every three months.
