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: hmF2 is a parameter derived from ionosonde data. It can be used to estimate the altitude of electron density maximum in the F2 layer of ionosphere. Performance Comment: Attributes for uncertainty and stability need still additional discussions.
