Accessing TEMPO Data
The TEMPO mission is providing a suite of air quality-related products, which are made publicly available and free of charge via the NASA Atmospheric Science Data Center (ASDC) TEMPO Data Products page and NASA Earthdata.
To learn more about TEMPO data products and how to get TEMPO data, please view the NASA Earthdata Webinar NASA Atmospheric Science Data Center “Finding Your TEMPO: An Introduction to the Mission, Products, and Data Services for Air Quality Observations over North America" and the associated presentation slide deck.
More information about TEMPO and the services the ASDC provides may be found in the TEMPO storymap.
Visualizing TEMPO Data
TEMPO data can be visualized using NASA Worldview for both Level 2 and Level 3 data.
TEMPO Level 3 nitrogen dioxide, formaldehyde and total ozone are available from NASA ArcGIS online. This ESRI blog post describes how to visualize TEMPO nitrogen dioxide data from ArcGIS Living Atlas of the World.
NASA Scientific Visualization Studio images and animations are available for
TEMPO Data Products
The table below shows the baseline TEMPO Level 1 – Level 3 data products. All Level 2 data products are produced at the native spatial resolution of 2.0 km x 4.75 km, except for the ozone profile product which is produced at a coarser resolution of 8.0 km x 4.75 km as this algorithm is very computationally expensive. Level 3 products are provided by resampling Level 2 products for a single scan to a 0.02° x 0.02° regular latitude-longitude grid (0.04° x 0.04° for ozone profile).In addition to the standard products, near real-time (NRT) (latency <3 hours) radiance, cloud, nitrogen dioxide and formaldehyde products became available in September 2025. NRT products were identified by the Satellite Needs Working Group (SNWG) as high-priority data products for federal agencies and other stakeholders. The NRT products are available for the past 14 days through NASA's ASDC TEMPO page and NASA Earthdata. Aerosol products are expected to become publicly available in early 2026.
