Optical resolving power
Correlative validation measurements
MetadataShow full item record
From the limb viewing geometry (i.e. tangential to Earth's surface and its atmosphere) it is possible to retrieve moderate resolution vertical profiles of various stratospheric trace gases. BrO and OClO profiles retrieved from the SCIAMACHY Limb measurements in a two step approach are presented and compared to independent groundbased, balloon borne and satellite observations. For the BrO profiles, a good agreement is found. For OClO profiles, there exist no correlative validation measurements so far. However, since OClO is an indicator for ClO, the OClO profiles derived from SCIAMACHY limb observations are compared to measurements of ClO by AURA-MLS and ODIN-SMR. Also, the effect of horizontal gradients in the trace gas distribution on the profile retrieval is investigated.
