Response of the neutral particle upper atmosphere to the solar eclipse of 7 March 1970
(Elsevier, 1972-04)
A series of five pitot probes were launched from Wallops Island, Va. (38[deg]N) in conjunction with the solar eclipse, 7 March 1970. Three soundings were programmed to occur at 40, 80 and 100 per cent obscuration of the ...
Chemistry of the thermosphere and ionosphere
(Elsevier, 1979)
The ionosphere offers an excellent laboratory for the study of atomic and molecular processes. Densities are low, permitting highly reactive species to accumulate in measurable quantities. Temporal and spatial scales are ...
The angular distribution of ion flux around an ionospheric satellite
(Elsevier, 1973-03)
Ion measurements from the Explorer 31 satellite were used to determine the angular distribution of ions around the satellite. The ion distributions were compared with the electron distributions measured on the same satellite. ...
The calculated and observed ionospheric properties during Atmospheric Explorer-C satellite crossings over Millstone Hill
(Elsevier, 1978-01)
The Atmospheric Explorer-C (AE-C) satellite passed almost directly over the Millstone Hill incoherent scatter radar station on 14 February 1974 and passed within the near vicinity of the station on 15 February 1974. ...
The electron heating rate and ion chemistry in the thermosphere above Wallops Island during the solar eclipse of 7 March 1970
(Elsevier, 1972-04)
An identical pair of thermosphere probes measured the N2 concentration and temperature, the ion composition and concentrations and the electron temperature up to 290 km about 30 min and 5 min before totality during the 7 ...
On the significance and utilization of secondary magnetizations in red beds
(Elsevier, 1978-01)
We document three cases of observed Quaternary or much older secondary magnetizations in red beds. A better than usual knowledge about past and present temperature conditions enables us to compare these secondary magnetizations ...
Theory of the piezomagnetic effect in titanomagnetite-bearing rocks
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1972-12)
The stress sensitivities S x and S R of susceptibility and remanence for titanomagnetite-bearing rocks are calculated in terms of magnetostriction constants λ 100 and λ 111 and anisotropy constants K 1 , K 2 of the magnetic ...
A comparison of the Gurevich et al. and the Liu-Jew wake models for the ion flux around a satellite
(Elsevier, 1975-04)
Observations of ion currents obtained by a retarding potential analyzer on board the Explorer 31 Satellite were used to compare the Liu-Jew and Gurevich et al. wake models with experiment. The quantitative degree of agreement ...
The effect of conjugate photoelectron impact ionization on the pre-dawn ionosphere
(Elsevier, 1973-12)
Theoretical calculations using photoelectron fluxes measured by a soft particle spectrometer on ISIS-2 as input data show that impact ionization by photoelectrons arriving from the sunlit conjugate region is insignificant ...
