UNIVERSITY OF WASHINGTON'S FLIGHT 1819 FOR SAFARI-2000

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

Date: 20 August 2000

UW Flight Number: 1819

Goals of Flight:

Sample smoke from prescribed fire in Medikwe Game Reserve (on South Africa-Botswana border: 26 deg 40 min 32.5 sec south/26 deg 14 min 08.2 sec east). Fire lit at 0815 UTC.

Period of Flight (engines on to engines off: UTC): 1124-1541

Location:

See above, plus transit flights from and return to Pietersburg, South Africa.

Weather Conditions:

Scattered cumulus on take off; clear on landing. Many fires and smoky in target area.

Accomplishments:

Full chemistry and physics on smoke from prescribed fire. Prescribed fire flared up during period on site. Many other fires in vicinity.
Good ambient sampling on site and in transit flights.
Passes beneath, in and above smoke plume (for radiometer measurements).

Main Instrument Malfunctions:

CAR filter wheel plus not full rotation capabilities. See also Squawk list.

Flight Scientist: Peter Hobbs
