Venus Atmospheric Composition in situ Data: A Compilation

Area of Science:

• Planetary Science
• Atmospheric Chemistry
• Venus Exploration

Background:

• Limited and scattered data on Venus' atmospheric composition and chemistry hinders research.
• Existing measurements vary in resolution, error margins, and are subject to reinterpretation.
• A centralized, reliable data source is crucial for advancing Venus science.

Purpose of the Study:

• To compile and present an extensive collection of published in situ data for Venus' atmospheric composition.
• To include remotely gathered, extrapolated, and modeled data for the lower atmosphere.
• To serve as a quick and comprehensive reference for Venus atmosphere measurements.

Main Methods:

• Compilation of published in situ measurements of Venus' atmospheric composition.
• Inclusion of remote sensing data and modeled/extrapolated data for the lower atmosphere.
• Organization of data into categories: noble gases, reactive gases, and isotopes.

Main Results:

• A comprehensive dataset of Venus atmospheric composition measurements is presented.
• Data includes measurements, error margins, techniques, altitudes, instruments, missions, and references.
• The compilation provides a unified view of available atmospheric data.

Conclusions:

• This paper offers a valuable, consolidated reference for Venus atmospheric data.
• The compiled data supports ongoing and future Venus atmospheric research.
• Facilitates a better understanding of Venus' atmospheric composition and chemistry.
