AB: We focus on selected CO enhancement events observed in TES data and also examine MLS and MOPITT data in the upper and lower troposphere. The events of interest include: the Siberian fires in July-Aug 2006, Indonesian fires in Sept-Oct-Nov 2006, Australian fires in mid-end Dec 2006 and the transpacific transports of pollutants in winter-spring 2007. The CO distributions near the event regions observed by the three instruments provide good opportunities for cross-instrument and cross-platform validations of the datasets. We describe the advantages, the limitations and the influence of the a priori assumptions to the retrievals for the nadir and limb instruments. The combination of the nadir and limb observations of CO provides a powerful datasets for studying pollution transport in different regions of the globe. Trajectory models are used to track the origins of the enhanced CO at different levels of the troposphere.
