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

Date: 23 August 2000

UW Flight Number: 1821

Goals of Flight:

Intercomparison of state, aerosol, and gas parameters with data from the Pietersburg GPS-brand rawinsonde, and also with the two South African Aerocommanders in a simultaneous vertical profile from the surface to 16,000 ft.

Period of Flight (engines on to engines off: UTC): 1138 to 1448

Location: Pietersburg, South Africa.

Weather Conditions:

Hazy. Isolated cumulus fractus, humilis and mediocris clouds. No winds at the surface, southerly winds aloft.

Accomplishments:

Intercomparison of Convair-580 and two Aerocommander measurements, and of Convair-580 state parameter with GPS-brand rawinsonde.

Main Instrument Malfunctions: See Squawk list.

Flight Scientist: A. Rangno

Approx. UCT Time (UTC = local time minus 2 hours)	Activity
1144 -1208	300 ft/minute climb to 700 mb.
1208-1217	Level flight at 700 mb with Aerocommanders.
1217 -1238	Descend to 9,000 ft then flew level flight for comparison in more homogeneous aerosol layer than at 700 mb.
1238-1257	Begin slow climb to locate top of haze layer and sample clean free troposphere.
1257-1357	Sample clean free troposphere.
1357-1400	Level flight to cumulus top to sample cumulus mediocris top.
1400-1419	Descend at 500 ft/min to 850 mb after exiting cumulus tops.
1419-1432	Low level runs for aerosol samples.
1432-1436	Depart for Pietersburg airport and land.
