GTE/Transport and Atmospheric Chemistry near the Equator-Atlantic

Project Description
An aircraft campaign was conducted from 21 September through 24
October 1992 as the NASA Global Tropospheric Experiment -
Transport and Atmospheric Chemistry near the Equator-Atlantic
(GTE/TRACE-A) to understand processes in the tropical
atmosphere controlling atmospheric chemical composition and
aerosols, in particular convective transports (see special 30
October 1996 issue of Journal of Geophys ical Research -
Atmospheres). Fourteen aircraft flights (NASA DC-8 and
Brazilian aircraft, including cooperation with an African
experiment conducted by European investigators: Southern
African Fire-Atmosphere Research Initiative) covered areas of
biomass burning, convective and continental outflow regions,
and areas of large-scale subsidence over and between tropical
South America and Africa. Aircraft measurements were supported
by enhanced surface and upper air meteorological observations,
a special ozone-sonde network, and satellite observations. The
experimental region extends ! from 40S-0 latitude a nd from
40E-70W longitude. (Fishman et al., 1996, JGR 101, 23865-23879;
Pickering et al., 1996, JGR 101, 23993-24012; Thompson et al.,
1996, JGR 101, 24251-24278). A discussion of TRACE-A research
at NASA Goddard Space Flight Center is available. This case
study presents data from 21 Sep 1992 to 24 Oct 1992 and covers
a region from 40S to 10N latitude and from 80W to 20W
longitude.
