| Zusammenfassung |
| The 2014–15 Holuhraun lava-flood eruption of Bárdarbunga volcano (Iceland) emitted
prodigious amounts of sulfur dioxide to the atmosphere. This eruption triggered a
long-distance episode of air pollution in September 2014, the first event of this magnitude
recorded in the modern era. We gathered a wealth of complementary observations from
satellite sensors (OMI, IASI), ground-based remote sensing (lidar, sunphotometry,
differential optical absorption spectroscopy) and ground-level air quality monitoring
networks to characterize both the spatial distribution of volcanic SO2 and aerosols as well as
the dynamics of the planetary boundary layer. We take advantage of this exceptional panel of
observations to quantitatively test our modeling ability to retrospectively simulate this event
of far-range air pollution. Although the model captures the correct temporal dynamics, it fails
to reproduce the intensity of the pollution. Paths worth exploring to get prepared to
accurately forecast a future large-scale event of volcanogenic air pollution are discussed. |
