Abstract : Satellite remote sensing data can provide valuable information on the broad-scale circulation of the polar regions and help in understanding changes on a range of time scales. Early results with sounder data have suggested that they can be used to accurately monitor tropospheric temperature changes, although further work is needed to fully interpret these data in the polar regions. Determining the movement of baroclinic zones and the associated synoptic and mesoscale disturbances is possible using sounder data and imagery, respectively. However, tracking of weather systems currently requires considerable manual processing. The production of a cloud climatology of the polar regions can be achieved using automatic processing of imagery and the resulting analysis could be important as an indicator of increasing moisture levels if a significant high latitude warming occurs.
