Pioneer Venus infrared radiometer - Design, implementation and preliminary resultsThe paper discusses the Pioneer Venus infrared radiometer design and operation. Its main function is to measure the thermal emission from the atmosphere at seven pressure levels above the Venus clouds, allowing a determination of the vertical temperature structure. In addition to the temperature sounding channels, there are two channels operating in the visible and near infrared to study the structure of the upper clouds, and a far infrared channel sensitive to water vapor in and above the clouds. The instrument can operate in four modes including a calibration sequence; by utilizing the spinning action of the spacecraft and short integration times, a substantial portion of the planet can be mapped within a 90 min data taking period centered about periapsis time. Temperature profiles retrieved during the course of the mission will clarify the dynamical processes in the upper atmosphere.
