EOL’s Capability

This document details the capabilities and technical developments of EOL in support of the RAINEX mission. It covers pre-flight equipment status, flight planning, in-mission operations like ELDORA and dropsonde management, and post-flight data quality control. Key communication protocols and the use of laptop-based systems for real-time data processing and decision-making are discussed. Collaboration among flight scientists and technical staff is emphasized to ensure effective data transfer and analysis.

  1. EOL’s Capability and Technical Development In RAINEXWen-Chau LeeNCAR/EOL15 Nov. 2004http://www.atd.ucar.edu

  2. 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

  3. Chat and Comm. laptop Communication Scientist Sat. Com. ADS WARDS CAPPI ELDORA LF ELDORA Scientist Flight Scientist

  4. LNA Before After

  5. 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.

  6. 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

  7. 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)

  8. 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
