Pre-LBA TRACE-A Data

Published by ORNL_DAAC | National Aeronautics and Space Administration | Catalog Last Checked: November 04, 2026 at 12:33 AM | Dataset Last Updated: November 03, 2026
This data set contains atmospheric chemistry and meteorological data from the NASA Transport and Atmospheric Chemistry near the Equator-Atlantic (TRACE-A) field study. The NASA TRACE-A study took place in August 1992 to determine the cause and source of high concentrations of ozone that accumulate over the Atlantic ocean between southern Africa and South America during the months of August through October. The processed, quality controlled and integrated data in the documented Pre-LBA Data sets were originally published as a set of three CD-ROMs (Marengo and Victoria, 1998) but have now been archived individually.
