The Polar Science Center at the University of Washington, Seattle has been providing estimates of Arctic Sea Ice volume and trends over the 1980-2010 period since March 2010. Ice Volume estimates are based on the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS). In this paper we, we examine PIOMAS ice volume estimates and provide uncertainty estimates for mean monthly ice volume and 30-year trends. The newly developed Sea Ice Thickness Climate Data Record as well as ice thickness and volume estimates from satellite are used. Ice volume estimates and trends are compared to global climate model integrations and uncertainties are examined in the context of climate change attribution
