| Zusammenfassung |
| Mid-infrared solar absorption spectra recorded by a state-of-the-art
ground-based FTIR system have the potential to provide precise total
O3 amounts. The currently best-performing retrieval
approaches use a combination of small and broad spectral O3
windows between 780 and 1015 cm−1. We show that for
these approaches the uncertainties of the temperature profile are by
far the major error sources. We demonstrate that a joint optimal
estimation of temperature and O3 profiles widely eliminates
this error. The improvements are documented by an extensive
theoretical error estimation. Our results suggest that mid-infrared
FTIR measurements can provide total O3 amounts with a
precision of around 1 DU, placing this method among the
most precise ground-based O3 monitoring techniques. We
recapitulate the requirements on the instrumental hardware and on
the retrieval that are needed to achieve this high precision. |
