Numerical models of the thermal budget earth's upper atmosphere in height range 90–500 km are developed. The main sources and sinks energy, including infrared radiative cooling vibrational‐rotational bands NO, CO 2 , OH, O 3 as well heating arising from dissipation turbulent energy eddy heat transport, taken into account. calculated temperature density profiles good agreement with respective Cira (1972) Jacchia (1977) models. It is found that collisions between atomic oxygen play an...
Following the flight of Venera 4 in October 1967, new in-situ measurements temperature, pressure and density Venus atmosphere were made on 16 17 May 1969 by 5 6 space probes. A description scientific devices an analysis results data are presented. From it is concluded that all performed are, general, internally consistent. The 4, Mariner flights which overlap altitude agree quite well. Based these spacecraft measurements, taking into account some ground-based additional assumptions, a...
Measurements of the temperature, pressure and wind speed in atmosphere Venus are reported. These were obtained with interplanetary station Venera 8, which was first entry probe to telemeter data from solar-illuminated side Venus. One component horizontal velocity obtained, for direction landing site sub-Earth paint,σ25° zonal direction. This found decrease σ100 m sec−1 at an altitude 50 km σ0 ground, flow day planet toward night all altitudes.
Although Venus is the planet most similar to Earth in size, mass, mean density, and amount of solar energy absorbed (see Table 1 ), for a long time it remained perplexing because even principal properties its surface atmosphere were not established. Venus's has prevented scientists from distinguishing details visible wavelengths. Ground-based spectroscopy allowed them estimate atmospheric parameters only at upper cloud deck, accuracy these estimates depended on assumptions about how...
A soft landing on the planet Venus was successfully accomplished by automatic interplanetary station Venera 7. The temperature of atmosphere measured during descent and at surface after landing. variation pressure with altitude determined down to combining measurements velocity derived from Doppler shift data descent, considering collected previously flights Veneras 4, 5 6.
Measurements of the flux downward solar radiation through atmosphere Venus and at planetary surface are reported. These were obtained with interplanetary spacecraft Venera 8 which landed on 22 July 1972 after a 55-min parachute descent atmosphere. A significant was found to penetrate entire thickness atmosphere, amount ground ∼1.5% that incident top The variation altitude indicates clouds have lower boundary an σ35 km.
