VEXAG Measurements Matrix Linked to Goals 2008Instructions for InputThe Venus Exploration Analysis Group (VEXAG) recently published the "Venus Exploration Goals, Objectives, Investigations, and Priorities 2007". In the next update of this report, VEXAG wishes to add a section that identifies critical laboratory measurements needed to fulfill the identified goals, objectives, and investigations. There are two types of laboratory measurements of relevance to Venus exploration. The first are measurements that are required to convert instrument radiances, voltages, etc. into natural parameters that characterize the Venus planetary system. For example, molecular cross sections are required to convert observed radiances into distributions of chemical constituents. The second type of important laboratory measurements are those required to interpret observations of Venus in the context of processes that control the Venus planetary system. An example are reaction rate constants required to interpret observed abundances in the context of the fundamental Venus atmospheric chemical cycles. VEXAG seeks community input on laboratory measurements of either type that are not currently available, but would be fundamental to the scientific success of future Venus exploration missions. A matrix of broad areas of Venus measurements that have been identified in the aforementioned VEXAG document has been prepared to assist the community in responding to this solicitation for information. This matrix is posted on the Web. In reviewing this matrix, please keep in mind that multiple observational approaches--both in situ and remote — may be capable of providing identified measurements. Ideas on needed laboratory measurements would be most useful to VEXAG if received by
