This paper presents the first middle atmosphere measurements of carbon monoxide densities, over the fairly large global coverage of the upper atmosphere research satellite (UARS). The measurements were made by the improved stratospheric and mesospheric sounder (ISAMS), which used a limb sounding infrared radiometer, looking in the region of 4.6 [mu]m. There are sources of CO from both the surface of the earth, and the upper atmosphere, which feed the middle atmosphere, in addition to photo-oxidation of methane which serves as a local source. There are very few simultaneous measurements to compare with to validate this data, but nonetheless the data does confirm some distribution features of CO predicted by 2D simulation.
