Net radiation measurements in the atmosphere of Venus indicate that the bulk of the atmosphere is radiatively cooling at high latitudes and heating at low latitudes. Similarity of features observed by all three probes indicate planetwide stratification. Flux variations within the clouds provide evidence of significant differences in cloud structure. A feature of unusually large opacity found near 60 kilometers at the north probe site is probably related to the unique circulation regime revealed…

Net radiation in the atmosphere of Venus: Measurements and interpretation
Net flux radiometer measurements in the atmosphere of Venus question the effectiveness of the greenhouse mechanism in maintaining the high surface temperature. To search for possible instrumental
Pioneer Venus Small Probes Net Flux Radiometer Experiment
The University of Wisconsin net flux experiment on the Pioneer Venus mission investigated the distribution of radiative energy deposition and loss which drives atmospheric circulation on Venus. The
Venus lower atmosphere heat balance
Pioneer Venus observations of temperatures and radiative fluxes are examined in an attempt to understand the thermal balance of the lower atmosphere. If all observations are correct and the probe
Measurements of thermal structure and thermal contrasts in the atmosphere of Venus and related dynamical observations: Results From the four Pioneer Venus Probes
Thermal structure of the atmosphere of Venus, and differences in structure with latitude (up to 60°) and clock hour (from midnight to 8 A.M.) have been measured in situ from an altitude of 126 km to
Venus Winds Are Zonal and Retrograde Below the Clouds
Winds in the lower atmosphere of Venus, inferred from three-dimensional radio interferometric tracking of the descents of the Pioneer day and north probes, are predominantly easterly with speeds of
The Thermal Balance of Venus in Light of the Pioneer Venus Mission
Instruments flown on the Pioneer Venus orbiter and probes measured many of the properties of the atmosphere of Venus which control its thermal balance and support its high surface temperature.

First Results from the Large Probe Infrared Radiometer Experiment
TLDR
Preliminary analysis has permitted us to estimate the infrared extinction coefficient profile attributable to aerosols, with respect to their visible profile, in the upper atmosphere of Venus and the water vapor mixing ratio below the clouds.
Infrared Remote Sounding of the Middle Atmosphere of Venus from the Pioneer Orbiter
Orbiter infrared measurements of the Venus atmosphere in the 60- to 140-kilometer region show very small diurnal temperature differences near the cloud tops, increasing somewhat at higher levels. The

Preliminary Results of the Solar Flux Radiometer Experiment Aboard the Pioneer Venus Multiprobe Mission
TLDR
The solar flux radiometer aboard the Pioneer Venus large probe operated successfully during its descent through the atmosphere of Venus, implying that about 2 percent of the solar energy incident on the planet is absorbed at the ground.
Infrared Image of Venus at the Time of Pioneer Venus Probe Encounter
TLDR
An image of the infrared emission from the Earth-facing hemisphere of Venus was obtained at the time the Pioneer Venus probes penetrated the atmosphere, revealing regions of rapidly varying polar features, a solar-related postdawn warm area, and a nonsolar-fixed nighttime warm area.
