TRACE-A: Aircraft and Sonde Atmospheric Chemistry Measurements
From September 21 to October 24, 1992, NASA's TRACE-A campaign collected data over the Atlantic Ocean to investigate high tropospheric ozone concentrations. The dataset includes measurements from 19 instruments aboard a DC-8 aircraft, such as lidar for aerosols and ozone, spectrometers for trace gases (CO, CH4, N2O, CO2), and data from dropped ozonesondes. It represents a focused, multi-instrument snapshot of atmospheric composition and dynamics in a critical region.
