The Tropospheric Emissions: Monitoring of Pollution (TEMPO) science team has completed reprocessing data with Version 04 (V04) algorithms, with the exception of the TEMPO Ozone Profile (O3PROF) data. V04 data are now available from August 2, 2023, to the present via NASA Earthdata Search. The V03 data will remain available through Earthdata Search until the TEMPO science team completes all reprocessing.
Note: TEMPO Ozone Profile (O3PROF) data from September 9, 2023, to August 27, 2025, are still being processed, with V04 data becoming publicly available as they are processed. O3PROF data may be processed non-sequentially, and several months of reprocessed data are already publicly available. This effort is expected to be completed sometime in 2027.
Also note that V04 August 2, 2023, data have recently been reprocessed and replaced; the Level 2 and Level 3 retrievals now use updated GEOS Composition Forecasting (GEOS-CF) a priori inputs. The file names remain the same, but new files can be identified by metadata production dates of September 2026.
V04 imagery for the TEMPO data is also available on Worldview. The reprocessed V04 data will be added to the TEMPO ArcGIS image services soon.
For inquiries about this or other TEMPO data releases, please email the ASDC team or post/view questions on the Earthdata Forum.
