Volcanic HazardVolcanic HazardVolcanic Ash and Sulfur Dioxide Cloud
Proximal Hazards
- Lava flow - Other flows - Toxic gases - Ash debris
Common elements
- GOES VIS, IR, UV channels - 12 micron channel
- Rapid detection of eruption is currently inadequate - Similar hot spot requirements as fire community
Spatial Temporal Phenomenon Data Threshold Optimum Threshold Optimum
Ash cloud IR 5 km 1 km 30 min 5 minVisible 1 km .5 km 30 min 5 minSounder 10 km 2 km 30 min 5 min

Dual Short Wave Thermal IR 2 - 4 micron
SO2 Ash Absorption 8.5 micron
Ultra Violet .3 - .4 micron
Common ThemesCommon ThemesIntegrated Systems - GOES, Polar - Operational and research satellites - Various spatial resolutions - Various refresh rates - In-Situ
Requirements process should address integrated approach
Rapid response coupled with higher spatial resolutionReal time access
Smooth the path from research to operations
