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.

TEMPO Data Access and Tools
Data collected by NASA’s Tropospheric Emissions: Monitoring Pollution (TEMPO) instrument enable precision monitoring of air pollution across the U.S.
The following are TEMPO standard data products and sampling rates:
- NO2, O3, aerosol, and cloud products sampled hourly, including eXceL O3 for selected target areas
- H2CO, C2H2O2, SO2 sampled 3 times/day (hourly samples averaged to get S/N)
- Product spatial resolution ≤ 8 km N/S x 4.5 km E/W at center of domain
- Signal/noise requirements met at SZA (Solar Zenith Angles) less than 50° for all products—and at angles up to 70° for NO2, clouds, and aerosols.
- Ozone profile products include 0–2 km O3, free tropospheric O3, and the stratospheric O3 column
