There will be a planned, all-day power outage of the Tropospheric Emissions: Monitoring Pollution (TEMPO) ground system from the morning of September 26, 2025, through the afternoon of September 27, 2025. TEMPO data ingest will begin once the power outage is completed. While there will be a delay in data processing, no data loss is expected.
Delivery of new Suomi National Polar-orbiting Partnership (Suomi NPP) satellite observations will cease on November 2, 2026. Data users should transition now to alternative products from NOAA-21 and NOAA-20.
