EOL’s Capability• Pre-flight
– Equipment status update– Flight planning
• During Mission– Operate ELDORA, ADS, and dropsonde– Monitor status of equipments– Assist flight scientist in making real-time
decisions
• Post-flight– Data quality control and data summary– Data analysis consultation

The ‘drown’ test (the Navy calls it a swim test) and, just as important, a medical clearance mean that a fraction of the scientific community will NOT be able to fly on the plane.

EOL Technical Development for RAINEX
• Download NOAA P3 LF data and upload LF images to NRL P3– Critical steps have been outlined
• Dropsonde capability– Intend to use the AXBT shoot with a modified
dropsonde insert
• Mobile ELDORA data processing capability– Post processing on a laptop
• Real-time display and control of the ELDORA system– Replace the proprietary VME hardware with
Linux PC based system (100Mbit ethernet)

Action Items
• Finalize the LF data transfer task list, identify responsible party and cost estimate
• Data transfer between Tampa and UM
• Identify acceptable means to display LF data in the flight deck
• Establish in-flight decision making procedure between pilots, flight scientist, and navigator on NRL P3
