Abstract

Measurements of O, He, and Ar from neutral gas mass spectrometers on four satellites (Ogo 6, San Marco 3, Aeros A, and AE-C) and inferred O2 and H densities from an ion mass spectrometer on AE-C have been combined with a neutral temperature and N2 density model, based on data from these four satellites and four incoherent scatter stations, to produce a global model of thermospheric composition in terms of inferred variations at 120 km. The data coverage is significantly improved over that of the similar Ogo 6 model in terms of altitude, seasonal, and solar parameters, and the usefulness is expanded by the inclusion of additional gas species. The overall data set covers the time period from mid-1969 to mid-1975. The seasonal He density variation is double that of the Ogo 6 model on average, with maximum variation in the northern hemisphere. Ar variations at 120 km tend to be in phase with temperature variations and inverse to the He, O, and H variations.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
