Volcanic Aerosols

Can have a significant impacton the atmosphere

Largest impact from conversionsof sulfur dioxide (SO2) tosulfuric acid (H2SO4)

Aerosols can cause surfacecooling and stratosphericwarming

Linked to the destruction ofozone

Summary

The ash plume from the Kelud eruption reached up to 25 km

There was a significant increase in SO2 in the region followingthe eruption

MODIS imagery shows a westward movement of the ashplume

RGB composites created with HYDRA can be used forvolcanic ash detection
