General theory of optimal trajectory for rocket flight in a resisting medium
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1973-02)
This paper considers the problem of optimizing the flight trajectory of a rocket vehicle moving in a resisting medium and in a general gravitational force field. General control laws for the lift, the bank angle, and the ...
Carbon dioxide and monoxide above the troposphere
(Elsevier, 1970-12)
The dependence of the atmospheric distributions of CO2 and CO upon the combined effects of photochemical production and loss, and transport is examined. It is found that, for CO2, deviations from complete mixing are possible ...
The nighttime distribution of ozone in the low-latitude mesosphere
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1973-12)
The intensity of stars at wavelengths in the Hartley continuum region of ozone has been monitored by the University of Wisconsin stellar photometers aboard the OAO-2 satellite during occultation of the star by the earth's ...
Thermal electron energy distribution measurements in the ionosphere
(Elsevier, 1973-08)
Results of electron spectrometer and cylindrical Langmuir probe measurements of ionospheric electron energy distribution in the range from about 0[middle dot]2 eV to 4[middle dot]0 eV are presented and discussed in this paper.
Photoelectron energy losses to thermal electrons
(Elsevier, 1971-01)
The photoelectron energy loss rate to the ambient electrons is discussed. It is shown that the conventional Butler and Buckingham expression has been incorrectly applied in photoelectron calculations. The appropriate energy ...
Theoretical N2 vibrational distribution in an aurora
(Elsevier, 1971-11)
The N2 vibrational distribution in an aurora is investigated. During the auroral bombardment the vibrational distribution is non-Boltzmann. The deviation from the Boltzmann distribution increases with increasing altitude. ...
On determining the ozone number density distribution from OAO-2 stellar occultation measurements
(Elsevier, 1974-09)
Stellar occultation data from the 2460 A and 2980 A channels of the OAO-2 stellar photometers have been used to derive the nighttime ozone number density distribution in the low latitude mesosphere. The nighttime ozone ...
Stellar occultation measurements of molecular oxygen in the lower thermosphere
(Elsevier, 1973-03)
Stellar ultraviolet light near 1500 A is attenuated in the Earth's upper atmosphere due to strong absorption in the Schumann-Runge continuum of molecular oxygen. The intensity of stars in the Schumann-Runge continuum region ...
Magnetic ordering of the polar airglow
(Elsevier, 1978-04)
The visible airglow experiment on the Atmosphere Explorer-C satellite has gathered sufficient data over the Earth's polar regions to allow one to map the geographic distribution of particle precipitation using emissions ...
