Arctic ocean expedition advances climate modeling

In-situ cloud, radiation, and surface energy budget data collected by a September 2014 expedition of the Japanese Research Vessel Mirai from a stationary point in the ice-free Arctic Ocean were used to investigate the skill of regional climate models. Although most near-surface meteorological parameters were adequately captured by most models, certain important discrepancies were identified, such as the failure to capture unstable low-level cloud stratification, and the partitioning of ice clouds and liquid clouds.
