UNIVERSITY OF WASHINGTON'S CONVAIR-580 FLIGHTS FOR SAFARI-2000

Date: 24 August 2000

UW Flight Number: 1822

Goals of Flight:

  1. Vertical profile (with "full" chemistry and physics measurements) over Inhaca Island, Mozambique, at time of Terra (0816 UTC) and ER-2 overpasses.

Period of Flight (engines on to engines off: UTC): 0638-1130

Location:

SAFARI instrumented tower at Inhaca Island (26 deg 01 min south/32 deg 55 min east). Vertical profile offset by about 9 nm to north of tower to avoid cloud over island.

Weather Conditions: Scattered small cumulus over land.

Accomplishments:

  1. Main goal achieved, but two higher levels (10,000 and 12,000 ft) of vertical profile not flown because of failure of one generator on Convair-580, and therefore no power for instruments and computers.
Instrument Malfunctions:

Lost power to research instruments and computers at 1004 UCT. See Squawk list.

Flight Scientist: Peter Hobbs
