Measurement of Trace Gases in the Atmosphere of Venus, Phase I

Completed Technology Project

Project Introduction

Southwest Sciences proposes to develop small, lightweight, low power instrumentation for the in situ balloon-borne measurement of several trace gases of importance in the atmosphere of Venus. Using low power vertical cavity diode lasers (VCSELs) at carefully selected wavelengths in the 2400 nm region, the instrument will be capable of simultaneous measurements of carbon monoxide, water vapor, hydrogen fluoride, carbonyl sulfide, and possibly sulfur dioxide. The Phase I effort will concentrate on identifying the best wavelength regions for measurement of multiple trace species with a minimum number of lasers (ideally no more than two), while establishing important design parameters for development of more rugged prototype instrumentation in Phase II.
