Quantifying active volcanic processes and mitigating their hazards with HyspIRI data
Michael Ramsey, University of Pittsburgh"
Collaborators: Andy Harris (UBP, France), Matt Watson (UB, England), Matt Patrick (HVO)!
Objectives: • Task 1:Quantify the magnitude of temperature-
dependent emissivity change for active basaltic surfaces using in situ field and laboratory IR data (fundamental science)
• Task 2: Determine the accuracy of high-temperature emissivity extraction at potential HyspIRI spatial resolutions and its impact on modeling of flow advance (applied science)
10/2015"
Requirements and Constraints • Start Date Preference: Fall 2016 or Spring 2017 • Surface Elevation: 0 to ~ 4000 feet • Weather Conditions: clear, no/low clouds • Cloud Cover (Max): 10% • Sun Angle Limits: not important • Ground Condition: dry • Satellite Overpass?: yes, Terra at ~ 11am/11pm LT • Sea State/Tidal Cycle: n/a • Additional requirements: coordination with field
team and HVO staff
Investigation Sites • Locations: Big Island
of Hawaii with specific targets centered on the active lava locations 1. lava lake at
Kilauea crater 2. active flows in the
East Rift Zone
Approach • The airborne data will be forward-modeled
using a quantitative resampling methodology. • During the overflights, ground-based
multispectral TIR data will be acquired from a newly-developed instrument.
• The combined data will be used to validate a correction approach for thermally-mixed HyspIRI data using VSWIR & TIR data.
• Results will be input into flow modeling to better monitor and predict future volcanic hazardous phenomena.
