New Systems

• Data system
• from 486-PC
  running DOS 6.0 (SEA M200)
• to Pentium III, 850 MHz processor running QNX
  4.25 (SEA M300)
• Consolidating serial I/O
• Porting inlet monitoring control
• Providing network file/data sharing time
  synchronization
• Cloud Aerosol and Precipitation Spectrometer
  (CAPS)
• CAS, 0.5-50um
• CiP, 25-1550um
• Pitot tube
• Temperature
• LWC hotwire, 0.01-3.0 g/m3
• Tof-AMS

15
Time of Flight Aerosol Mass Spectrometer
(ToF-AMS)Aerodyne Research Inc.

• Similar in concept to old AMS currently used on
  the RAF-G1
• Use of ToF-MS allows full mass spectrum to be
  recorded for each particle vaporization event
• Benefits
• chemically speciated mass distributions
• more sensitive ensemble particle composition
• single particle composition

16
Development/Future Systems

• Turbulence
• Improved aerosol inlet
• Fast Water Vapor
• Counterflow Virtual Impactor (CVI)
• Stabilized platform for radiometry
• Zenith
• nadir
• Drop Sondes
• Power modifications
• What I need input on priorities
