| Zusammenfassung |
| A new retrieval method (called "Onion Peeling DOAS") has been developed to derive
stratopheric profiles of atmospheric constituents from solar occultation measurements of
the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY
(SCIAMACHY). This method is intentionally kept simple and based on a combination of an
onion peeling approach with a modified DOAS (Differential Optical Absorption
Spectroscopy) fit. The method has already been successfully used to derive stratospheric
water vapour profiles. However, the Onion Peeling DOAS method can also be applied to
other atmospheric constituents. Here, we will present first retrieval results for methane (CH4)
and carbon dioxide (CO2). |
