NASA has trace gases/trace species datasets that help researchers characterize the makeup of the atmosphere. Access a range of data and data tools such as AppEEARS, FIRMS, and Giovanni to make the most of trace gases/trace species data.
Many NASA observation methods—platforms, instruments, and space geodesy techniques—provide data that improve our understanding of trace gases, including NASA's Tropospheric Emissions: Monitoring Pollution (TEMPO) instrument, featured below.
