• Generating and maintaining algorithms/software for the calibration and validation of AVIRIS data
• Reporting AVIRIS calibration status

• Year-round data acquisition planning with the investigator, Dryden, AVIRIS task, and NASA HQ
• Maintain AVIRIS flight planning reports in conjunction with Dryden for investigator updates
• Represent and communicate with investigator before, during and after each data launch and flight
• Post-flight debriefing of the pilot for data acquisition record
• Transfer of ship disk and flight log to the AVIRIS Instrument Ground Data System (IGDS) at JPL for data decommutation and data processing
• Report AVIRIS data status to Dryden following analysis at the data facility

• Management of the IGDS activities and logistics
• Decommutation and archiving of AVIRIS data
• Monitoring instrument performance from acquired data
• Generation and upload of quick-look images to AVIRIS website
• Execute data processing pipeline to produce L1B and L2 data products
• Monitoring quality of L1B and L2 data products
• Maintain AVIRIS specific software
• Maintenance of system hardware and software
• Limited support to visiting scientists
• Distribution of L1B and L2 data products via FTP or hard drive to Investigator(s)
• Import L1B and L2 data products into AVIRIS Flight Locator Tool
• Support of AVIRIS engineering analysis
• Generate backup of raw data to LTO Tape Library System

• Engineering operations task management, planning, scheduling and oversight
• Logistical planning and transportation for AVIRIS and ground support equipment shipping
• Logistical planning for AVIRIS engineer and technician launch site support
• AVIRIS engineer and technician support for each launch
• Pre-flight preparation and monitoring of AVIRIS
• Post-flight care and monitoring of AVIRIS
• Historic monitoring of AVIRIS instrument performance
• Semiannual spectral calibration measurements
• Semiannual radiometric calibration measurements
• Semiannual geometric calibration measurements
• Report calibration measurements

• Maintenance of ground support equipment
• Maintenance of AVIRIS instrument diagnostic equipment
• Routine maintenance of AVIRIS during data operations
• Evaluate level of preventative maintenance required
• Preventative and routine maintenance of the AVIRIS sensor during non-data operations
• (*.html file)
• Maintenance of AVIRIS documentation and spare parts
• Resolution of anomalies affecting the optical, analog and digital electrical, mechanical, cryogenic, and calibration subsystems of the AVIRIS sensor

• Results of these activities will be reported at the AVIRIS team meetings, communication to the AVIRIS Technical Group Supervisor, and through written documentation where requested.
