NOAA/AOC Support Requests for RAINEX

• Capabilities aboard the RAINEX NOAA P-3 aircraft
  should be the same as those available during the
  BAMEX Project.
• LF radar packets on aircraft LAN
• Project provided computer for radar processing
• Project provided processing software
• Radar data products
• Preferred data stream in compressed and
  geo-referenced format for continuous download to
  Operations Center. This would give the operations
  folks the most flexibility to prepare a composite
  image with satellite, aircraft track and
  annotation. Several considerations here
  including size of the datastream, practicality
  for continuous download, etc.
• Possible compressed gridded format radar data
  file of a single 360 sweep from LF radar.
  Complete gridded file to be downloaded each 5
  minutes to the Operations Center.
• Need to determine compressed data stream and/or
  gridded product file size
• Need to determine real (as opposed to advertised)
  download rate via satellite system
• Download aircraft position and flight level
  (selected) data
• Install chat and configure for flight scientist
  use aboard both aircraft

NRL Support Requests for RAINEX (Communications
Related)

• Capabilities aboard the RAINEX NRL P-3 aircraft
  should be the same as those available during the
  BAMEX Project.
• Position information and selected flight level
  data to be continuously downloaded to Operations
  Center
• Chat capabilities to be available for flight
  scientist use aboard the aircraft.
• Other capabilities to aid real time coordination
• Provide display on the aircraft for the ELDORA
  scientist position and possibly on the flight
  deck
• Need to determine real (as opposed to advertised)
  upload rate via satellite system. (This has a
  major bearing on the size frequency of image that
  can be provided to update NOAA LF radar,
  satellite and flight track composite)
• .

7
Operations Center Real time Support Tasks

• Data and products to be downloaded from aircraft
  include
• All aircraft position,
• All aircraft flight level data,
• LF radar data in radar format (continuous) or
  compressed gridded file (5 minute intervals)
  from NOAA aircraft
• Other data and products include
• High-resolution GOES in normal or rapid scan
  mode.
• Other special products from various sources (e.g.
  HRD/NHC)
• Products Uploaded to aircraft
• Satellite/NOAA LF radar composite with completed
  aircraft track information back 30 minutes and
  proposed future track of NRL out 30 minutes
  (including direction and end points) Other
  annotation including hurricane motion, band
  rotation and cell propagation information should
  be included.
• Other general information including cell/band
  intensification, new growth, etc. via separate
  schematic diagram or chat
• In the absence of LF radar data in the vicinity
  of NRL, provide satellite image with annotation
  as noted above.

Summary of Key Communications Issues

• LF radar data availability on NOAA P-3 aircraft
  LAN
• Actual Bandwidth capacities on all aircraft
• Interface RAINEX provided computers on NOAA
  aircraft
• Real-time availability of aircraft track
  information
• Transmission of LF geo-referenced data or product
  to the operations center
• Determination of realistic composite product
  update rate

RAINEX Mission Planning Key Considerations

• Alert sequence and lead times for RAINEX proposed
  operations
• Timing of staging of NRL P-3 to AOC
• Flight track planning and updating (radar and
  dropsondes)
• Departure sequence for NOAA and NRL aircraft
• Collaboration on dropsonde mission planning with
  NHC/HRD (advanced)
• Dropsonde coordination (real-time)
• Mission planning process with contingencies in
  play (e.g. deployment with Caribbean or Pacific
  Ocean ops)
