Validated: 12/7/25 Source: New source to be determined
General Comment: Values discussed with ET-SWX. Submitted by Kirsti Kauristie AA 1.3 POC. Confidence: reasonable
Def: :Not firm, but based on a strong heritage of experiments with similar data
Application Area Comment: Horizontal Coverage Comment: Global coverage can be achieved by long term satellite measurements. Data from individual orbits can be used to validate thermospheric models in research and near-real-time operations.
