We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

Trace Gases/Trace Species Data Access and Tools
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.

Featured Trace Gases/Trace Species Observation Method: TEMPO
The Tropospheric Emissions: Monitoring Pollution (TEMPO) instrument is a high-resolution, visible and ultraviolet light spectrometer aboard the Intelsat 40e platform. TEMPO monitors major air pollutants, such as ozone and nitrogen dioxide, across North America every daylight hour.
Videos from NASA’s Scientific Visualization Studio reveal the brilliant view from the agency’s newest pollution-detecting sensor.
