Flight Summary Report

Author: Steve Platnick
Mission Scientist: Dr. Michael King
ER-2 Pilot: Jan Nystrom
Takeoff: 0705 (UTC)
Landing: 1310 (UTC)
Duration: 6:05 (h:mm)

Objective and Summary:

  1. Overfly expected stratocumulus cloud decks off the Mozambique Channel with SAWB JRB (outfitted for cloud microphysical sampling) coordinated with Terra overpass,
  2. Overfly powerplants east of Johannesburg (Witbank, Secunda and Tutuka), along with industrial sites south of Johannesburg and the Vredefort dome (ancient impact crater site).

The NCAR CCN counter was returned to SAWB Aerocommander JRB aircraft after the loss of the University of Washington CV-580 aircraft in Namibia due to mechanical problems. Along with cloud probes (hot wire, FSSP), JRB provides a platform for cloud microphysical validation. Because of a late overflight clearance for Mozambique, JRB was unable to take off in time to coordinate with the ER-2. As an alternate, JRB sampled a stratocumulus deck in the vicinity of Pietersburg at the time of the Terra overpass. Cloud tops were about 9,500 ft. at the time of the overpass to over 12,000 ft. a couple of hours later; cloud base was about 6500 feet. A smoke plume entering cloud base was sampled. Rain/drizzle was noted in one isolated region.

Key Flight Legs:

The ER-2 flight tracks were oriented parallel to Terra with a 0840 UTC overpass. The Terra ground track was approximately 600 km west of the flight tracks (47 degree viewing angle, within MODIS swath). The flight legs over the power plants were reported by the pilot to be overcast and the legs were aborted.

Meteorology:

A high to the south of the South Africa is extending a ridge northwards along the eastern seaboard. A weak upper trough is to the east of the subcontinent with an upper ridge developing over the country. Moist cool air exists in the lower levels over northeastern and northern South Africa, southern Zimbabwe, southern Mozambique and Malawi. Offshore flow along west coast, but onshore over northern Namibia.
