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.

NRL P3 Scientific Positions

• Flight Scientist – Wen-Chau Lee & Dave Jorgensen

• ELDORA Scientist – Michael Bell & Hua-Qing Cai

• Communication Scientist – UW and UM graduate students

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
