Ground-based remote sensing of carbon dioxide and methane in the Arctic using Fourier-transform infrared spectrometry
The abundances of the atmospheric greenhouse gases carbon dioxide and methane are monitored across the globe by a network of ground-based solar absorption Fourier-transform infrared spectrometers, the Total Carbon Column Observing Network (TCCON). In this dissertation, the existing measurement time...

The abundances of the atmospheric greenhouse gases carbon dioxide and methane are monitored across the globe by a network of ground-based solar absorption Fourier-transform infrared spectrometers, the Total Carbon Column Observing Network (TCCON).

In addition to the near-infrared TCCON measurements, spectra in the middle-infrared are routinely taken in Ny-A lesund. The newly obtained data from these spectra are compared to the standard TCCON retrieval. Additionally, in the high Arctic, measurements of solar absorption spectra are not possible in winter, because the Sun is permanently below the horizon.
