Validated: 12/7/25 Source: New source to be determined
General Comment: Confidence: reasonable
Def: :Not firm, but based on a strong heritage of experiments with similar data
Application Area Comment: Values discussed with ET-SWX. Submitted by Kirsti Kauristie AA 1.3 POC. Horizontal Coverage Comment:
Observation Comment: h'F is a parameter derived from ionosonde measurements. It can be used to estimate the true altitude of the maximum electron density in the F-layer of ionosphere. Performance Comment: Attributes for Uncertainty and stability need still some discussions.
