The TEMPO mission will provide a suite of air quality-related products, which will be made publicly available and free of charge via the NASA Atmospheric Science Data Center (ASDC). The table below show the planned TEMPO Level 0 – Level 4 data products, including proposed products in bold font. Ozone profile product is provided at coarser resolution of 8.0 km x 4.75 km due to requirement of co-adding four pixels to achieve increased signal-to-noise in the final product. Near real-time (NRT) products (latency < 3 hours) have been proposed for cloud, nitrogen dioxide (NO2), formaldehyde (HCHO), sulfur dioxide (SO2), and aerosol products.
