Total Carbon Column
Observing Network

TCCON is a network of ground-based Fourier Transform Spectrometers recording direct solar spectra in the near-infrared spectral region. From these spectra, accurate and precise column-averaged abundance of CO2, CH4, N2O, HF, CO, H2O, and HDO are retrieved.

TCCON provides an essential validation resource for the Orbiting Carbon Observatory (OCO), Sciamachy, and GOSAT.
