Flight Readiness ReviewALIVE (Aerosol LIDAR
Validation Experiment)

• August 31, 2005
• Beat Schmid, BAER Institute
• Joseph Ben Hovelman, Sky Research
• Roy Johnson, NASA ARC

2
Background

• ALIVE is a DOE funded mission utilizing NASA
  instruments and staff.
• DOE also conducts safety reviews for the ALIVE
  aircraft in addition to the NASA safety review.
• Dr. Beat Schmid won DOE peer reviewed funding for
  ALIVE and is the Project Manager as well as the
  PI for the Ames Sunphotometer during the mission.

3
Purpose

• Validate Aerosol Extinction Profiles over ARM CRF
  in Oklahoma derived from ground-based Raman and
  Micropulse Lidars
• Validate Aerosol Extinction Profiles derived from
  ARM Cessna 206 in-situ aerosol plane (IAP)
• Derive aerosol optical properties by combining
  AATS-14 and RSP measurements.

  31 will arrive at Moffett Field
• September 8-10 Instrument integration (AATS-14,
  NavMet, Aplanix POS, and RSP) into J-31
• September 10 (Saturday) J-31 test flight (30 to
  45 minute duration)

AIRPORT FACILITIES
Aircraft modification, sensor installation, and
maintenance activities are based at the Sky
Research hangar at Ashland Airport (S03) located
in southern Oregon. Sensor re-installation and
test-flight will be based out of NASA
Ames-Moffett Field (NUQ) in California.
Instrument deployment flights to the DOE SGP CRF
will be based at Ponca City Regional Airport
(PNC) in north-central Oklahoma.

Operations

• Flights centered on ARM CRF 36.60N, 97.48E.
• Timeframe Sep. 11 22, 2005
• 10 days on site
• 23 on-site research flight hours
• 10-15 short duration flights
• VFR only, avoid sun obscured by cirrus clouds
• Two types of flight patterns

10
Type 1 Regular ALIVE Flights
11
Type 2 Intercomparison Flights

• J-31 will wait until Cessna starts its 15K leg
  then take off (25 min lag)
• Vertical separation is always more than 1500 ft
• ATC radar flight following at all times
• Continuous radio contact between 2 aircraft
• J-31 will RTB immediately if radio contact is
  lost
• 3-4 such flights

12
AIRCRAFT DESCRIPTION

• Jetstream 31, N22746
• Pressurized, twin-engine turbo prop aircraft,
  modified to provide an Airborne Sensor Platform
  for research, survey, and reconnaissance missions
• Large, wide cabin with standing headroom and
  oversized cargo pod for flexibility in deploying
  multiple sensors
• A 10 NVG observation bubble window, dual SAT COM
  communication, dual GPS navigation, 8 position
