Flight Mission Details

By Peter Hobbs

by Peter Hobbs

Goals of Flight:

- Sample smoke from prescribed fire in Madikwe Game Reserve on South Africa-Botswana border (26 deg 40 min 32.5 sec S; 26 deg 14 min 08.2 sec E). Fire lit at 08:15 UTC.

Accomplishments of Flight:

- 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).

 Location:

- WSW from Pietersburg to the Madikwe Game Reserve.

Weather Conditions:

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

Instrument Problems:

- CAR filter wheel plus not full rotation capabilities.
