An Upper Limit for Atmospheric Carbon Dioxide on Mercury
Abstract
It has been possible to reduce sharply the upper limit on CO1 in the atmosphere of Mercury, due to the strength of the 12000 A CO1 bands which can now be reached at high dispersion with the Carnegie- RCA S-1 image tube. We can with some confidence assign an upper limit of 0.58 m-atm (possibly as low as 0.27 m-atm) to the abundance of CO1 on Mercury at the time of these observations. This implies an upper limit, in March-April, 1967, of about 0.04 mb to the surface partial pressure of CO2.
