Tropospheric Emissions: Monitoring of Pollution (TEMPO) Version 04 (V04) Level 1, 2, and 3 data are now available from the NASA's Atmospheric Science Data Center (ASDC) via Earthdata Search. This data release includes new L2 and L3 ozone profile beta products.
TEMPO V04 data are available starting from September 17, 2025. TEMPO V03 data (from August 2, 2023, to September 16, 2025) are being reprocessed with V04 algorithms, with V04 products becoming publicly available as they are reprocessed. The V03 data will remain available through Earthdata Search until the TEMPO Science Team completes the reprocessing.
Included in this release are the following provisional and beta products.
