| Zusammenfassung |
| Over the last decade ground-based remote sensing measurements of CO2 have been
established as an important component in the global observing system for greenhouse gases.
Since 2004 the Total Carbon Column Observing Network (TCCON) sites have provided CO2
retrievals in the near-IR region. CO2 can also be retrieved in the mid-IR spectral region and it
would be of great benefit to use these spectra to produce CO2-data of sufficient precision.
With this, 20 years of additional observations obtained in the mid-IR at a suite of FT-IR
sites of the Network Detection of Atmospheric Composition Change (NDACC)
will be accessible. We investigated a series of different CO2 microwindows in the
mid-IR spectral region and present results from the most promising candidates for a
showcase FT-IR site (Ny Alesund). Limitations of the approach are outlined and the
feasibility of a future Mid-IR CO2-product of sufficient precision is discussed. |
