Mission Summary
Date: June 22, 1995
ER-2 Flight Number: 95-126
Deployment: ARC-Jun95
Flight Location: Death Valley, CA; Cuprite, NV
Principal Investigators: Dr. James Crowley (USGS), Dr. Roger Clark (USGS), Dr. Robert Green (JPL), Dr. Fred Kruse (AIG)
Additional Sensors: 12" RC-10 (CIR), AVIRIS
Objective: Data used with ground based observations to study debris flows and other mass-wasting geologic events associated with hydorthermally-altered rocks at selected volcanic sites (Crowley). Support Shuttle Imaging Radar in developing data sets for lithographic mapping (Kruse). Data used to validate and calibrate the AVIRIS instrument for eventual comparison to data collected by the HSI sensor onboard the Lewis satellite (Green). Assist the National Park Service in aquiring information concerning soil and rock composition; vegitation type, density, and vigor; animal and plant habitat; anthropological impact; and other ecological data (Clark).

Data Evalutation
Track 2, channel 31, shows some aircraft noise. Track 4, ports 3 and 4 show LN2 blowoffs (banding across flightline). This is particularly bad in port 4. Port 4 also shows dropped scanlines. Both problems only occur early in the flightline, remainder of flightline appears OK. Track 6 smeared at start of flightline.
