Search Workshop on Large-Scale Atmosphere–Cryosphere Observations

Abstract

Although certain regions of the Arctic have experienced periods of decadal warming during the last 100 years, recent decades show an ongoing suite of Arctic-wide, interrelated atmospheric, oceanic, terrestrial, and human dimension changes. A major workshop conclusion stresses the necessity for coordination between arctic disciplines to form a continuing and enhanced dataset of arctic change. A major workshop recommendation is to increase the use of past and evolving datasets for understanding arctic change through, for example, an arctic change protocol, an aaaarctic system reanalysis, timely intercalibration of satellite products, and multidisciplinary, multiregional analyses. Understanding of the Arctic can improve change detection due to the roles of vegetation type, sea ice, and other feedbacks in providing a multiyear memory for the climate system.
