NOAA POES SEM-2 Data Discontinuation

The NOAA Polar Operational Environmental Satellites (POES) NOAA-15, -18, and -19 are nearing the end of their Extended Life phase. In preparation for the decommissioning of these satellites, NOAA is discontinuing data collection on June 16, 2025 at 1800 UTC for most instruments. This includes the Space Environment Monitor (SEM-2) suite of instruments and products. After this time no new POES SEM-2 data will be available. SEM-2 data from the Metop-B and -C spacecraft will continue to be collected and available via existing NOAA dissemination methods.

Data access to previously collected POES SEM-2 data will continue to be available via: https://www.ncei.noaa.gov/products/poes-space-environment-monitor.
