We describe saellite observations and analyses leading to the abundance of neutral atomic hydrogen near 300 km and its horizontal distribution with latitude and local time through the summer thermosphere. These H concentrations were derived from the charge-exchange equilibrium relationship between hydrogen and oxygen atoms and ions, with basic in situ measurements accomplished in the F region with the Atmospheric Explorer-C (AE-C) satellite around the June 1974 solstice near a solar minimum. Critical observational information concerning the low ion densities of H(+) was provided by the magnetic ion mass spectrometer (MIMS) on board this spacecraft. We demonstrate reasonable consistency of the broad horizontal behavior with other available observations and the mass spectrometer/incoherent scatter 1986 atmospheric model, both for the extensively studied diurnal variation at low latitude and the lesser-known latiudinal dependence. We include a brief discussion regarding the observed relationship between the local H concentration and the temperature as they vary through the summer thermosphere, noting distinctly different power law behaviors in the hydrogen distribution for temperatures lesser and greater than approximately 800 K.
