Description

Arctic warming rates exceed twice the global average, but these atmospheric processes are not accurately represented in earth system models, due to a lack of year-round observations in the central Arctic. The Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) field campaign supported by Los Alamos National Laboratory for the Atmospheric Radiation Measurement user facility will respond to these challenges; starting September 2019, an intensive icebreaker-based observatory will freeze in and drift with Arctic sea ice for a full annual cycle, taking atmosphere, oceanic, and biosphere measurements. Developed in conjunction with Germany’s Alfred Wegener Institute, the MOSAiC science objective aims to measure atmosphere-ice ocean processes in all seasons, which influence the flow of energy through the coupled artic system. As the largest of its kind, the MOSAiC campaign will amass unprecedented data and inform crucial regional and global-scale models.
