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

Date: 10 August 2000

UW Flight Number: 1810

Period of Flight (UTC): 1127-1522

Goals of Flight: Test of instruments, systems and procedures.

Location: West through north quadrant from Pietersburg out to about 90 nm.

Weather Conditions:

Well mixed boundary layer. Top of boundary layer near 10,500 ft. Scattered cumulus; bases near top of boundary layer, maximum cloud tops near 15,000 ft.

Accomplishments:

1) Physical and chemical measurements (including filter and can sampling etc.) in free troposphere.

2) Same as # 1 above but near and above top of boundary layer.

Main Instrument Malfunctions:

Tansvector not calibrated.

Ophir, Nox, CN.

Audio tape ran out (??).

Flight Scientist: Peter V. Hobbs

Approx: UTC Time (UTC=local time minus 2 hours)	Activity
1127	Take off from Pietersburg, South Africa.
1127-1152	Head north and climb to 11,000 ft to free troposphere.
1152-1218	Sampling in free troposphere. Ionic and carbon filters on continuous sampler plus 1 HC can sample. Test of cloud physics probes in small cumulus.
1330 - 1500	9,500 ft in haze near top of boundary layer (light scattering about 0.00002 per meter). Carbon and ionic filters on bag-house, Eatough filters and Buseck screen on continuous sampling. HC cans, DMPS.
1522	Land Pietersburg, South Africa.
