POLARCAT addresses important gaps in knowledge of the climatically sensitive polar regions, i.e., how they respond to a complex summation of surface exchange processes, vertical transport, unique Arctic air chemistry, and import from and export to midlatitude regions. The task incorporates intensive aircraft experiments, research ship cruises, monitoring activities at surface stations, ground-based remote sensing, balloon releases, satellite measurements, and a range of different models to test the understanding of Arctic processes against the measurement data sets. The task's efforts have led to a special issue in Atmospheric Chemistry and Physics.
