CE S Hazard Requirementsfrom the Perspective of theDisaster Management Support Group Levin Lauritson, NOAA, USA
Disaster Management Support Group Objective: To support natural and technological disaster management on a worldwide basis, by fostering improved utilization of existing and planned Earth observation satellite data
Hazard Team Coordinators Earthquake ESA, NPA/UK Fire USDA, UNEP, CFS/Canada Flood CCRS, NOAA Landslide CCRS, NIED Oil spill NRSC/UK Ice NIC/USA, CIS/Canada Volcanic hazards NOAA,USGS, U. of Reading/UK
Dimensions of Disaster Management User Level Disaster Management Category Activity Status International Mitigation Research Regional Preparedness (Warning) Demonstration National Relief/Recovery Operational State Local Other User Services Data and Products Observations
Fire Fuels Mapping Risk Assessment Detection Monitoring (System) Mapping Burned Area Recovery Smoke Management Biomass Burning Detection (within) 5 minutes Repeat time 15 minutes Spatial resolution 250 meters False alarm rate (max.) 5% Fire intensity Real time transmission to local ground stations or information networks
Flood River Floods Coastal Floods (Tsunamis) Urban Floods Flash Flood (Excessive Rainfall) Ice Jams

Ice Icebergs, Sea Ice, Lake Ice GOES used by several national ice services to monitor ice in lower latitude seas and lakes Lower latitudes do not suffer from persistent illumination problems Spatial resolutions of 1 km (VIS) and 4 km (IR) insufficient for detailed ice mapping Requirement Threshold Optimum Ice Edge 750m, daily 100m, 6 hourly Detection, 100m, daily for avoidance
Volcanic Hazard Volcanic 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

Volcanic Hazards GOES Channel Requirements Dual Long Wave Thermal IR 11-12 micron Dual Short Wave Thermal IR 2 - 4 micron SO2 Ash Absorption 8.5 micron Ultra Violet .3 - .4 micron
Common Themes Integrated 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
