| Zusammenfassung |
| 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. TCCON measurements are linked to WMO calibration scales by comparisons
with co-incident in situ profiles measured from aircraft. For CO2, TCCON achieves 1-sigma
precision of typically 0.2 ppm for single measurements, and a network wide comparability of
better than 0.1
In this paper we present an overview and the current status of the network, ongoing
efforts to improve network coverage, precision and accuracy, and examples of TCCON data
and their application.
Further information about TCCON and a full list of sites and TCCON partners is
available from the TCCON wiki, https://tccon-wiki.caltech.edu/ and Wunch et al.
