文摘
- •
OMI observed an SO2 plume 4–6 times more often during extrusion than quiescence.
- •
Ground measurements suggest that increased SO2 emissions do not account for this.
- •
Increased altitude of SO2 plume during extrusion offers alternative explanation.
- •
Plumes reach 1.5–6 km, lofted by hot new lava dome & co-pyroclastic flow clouds.
- •
Ground- and satellite-based observations have inverse optimal retrieval conditions.
