Delivery of Suomi National Polar-orbiting Partnership (Suomi NPP) satellite data products will cease on November 1, 2026. Data users should transition now to alternative products from NOAA-21 and NOAA-20.
Suomi NPP data announcement
NASA's Aura platform detects the unique spectral signatures of trace gases in the atmosphere, including pollutants such as ozone, carbon monoxide, and aerosols. Measurements made by Aura's four instruments help scientists answer questions about ozone trends, air quality changes, and how these fluctuations contribute to climate change.
