SFMR
SFMR data may be questionable at high altitude
due to algorithm assumptions Reliability of data
undetermined in winter environment High altitude
data acquired during Summer T-Parc but results
not yet reported.
12
Capabilities/Range

• Synoptic max Altitude is 34,000 ft
• (highest practicable in winter storms)
• Range
• Max 13.5 hour _at_ 30,000 ft 4,200nm
• 1 hour transit time to/from track and then 6-10
  hours along track
• Dependent upon assigned track

13
Limiting Factors

• Maintenance
• Dual tasking
• One crew and one aircraft

14
Operating Cost

• Cost
• 100 operational hours for 30 days 250K
• 200 operational hours for 60 days 500K

15
Benefits WSRP

• Objective
• Improve forecasts of significant winter weather
  events through targeted observations in data
  sparse Northeast Pacific Ocean
• Adaptive approach to collection of observational
  data
• Only prior to significant winter weather
  events of interest
• Only in areas that influence high impact event
  forecasts
• Results
• (Past 9 yrs) 70 of targeted numerical
  weather predictions improve
• 10-20 error reduction for high impact event
  forecasts
• 12-hour gain in predicting high impact events
  earlier warnings possible

16
Additional Information

• SatCom Ground Station at Guam or JTWC
• How do we obtain tasking (CARCAH)
• Possible alternate staging areas
• Buoy drops
• Duration - 30 or 45 or 60 days
• When do you want us on-station
