| Zusammenfassung |
On 4 June 2011 an eruption of the Chilean volcano complex Puyehue–Cordón Caulle injected large amounts of volcanic ash into the atmosphere
and affected local life as well as hemisphere-wide air traffic. Observations
of the Infrared Atmospheric Sounding Interferometer (IASI) flown on board of
the MetOp satellite have been exploited to analyze the evolution of the ash
plume around the Southern Hemisphere. A novel singular vector-based
retrieval methodology, originally developed for observation of desert dust
over land and ocean, has been adapted to enable remote sensing of volcanic
ash.
Since IASI observations in the 8–12 μm window are applied in the
retrieval, the method is insensitive to solar illumination and therefore
yields twice the observation rate of the ash plume evolution compared to
solar backscatter methods from polar orbiting satellites. The retrieval
scheme, the emission characteristics and the circumpolar transport of the
ash are examined by means of a source–receptor analysis. |
