Evidence for long-range transport of carbon monoxide in the southern hemisphere from SCIAMACHY observations

This paper gives an overview of the results published by [1],[2], and [3]. The precision of the SCIAMACHY carbon monoxide (CO) total columns depends on the random instrument-noise error and is generally within 10% for monthly means. SCIAMACHY CO total columns agree well with chemistry-transport model simulations using the GFEDv2 biomass-burning emission data base. Enhanced CO columns are seen with SCIAMACHY over Australia during its biomass-burning season in local Spring. It is shown that the enhancements over Australian
biomass-burning areas contain a large contribution of CO from South American biomass-burning regions. The results indicate that SCIAMACHY can be used to study both longe-range transport and emission sources of CO.
