Please note : Original data was obtained from the five respective modeling centers. Each set of model output has been interpolated to a common grid. The grids are 2.5 x 2.5 deg. lat/lon for the air temperature and precipitation data, 1 x 1 deg. lat/lon for the sea ice fraction data. The data structure, dimensions, and metadata can be viewed by selecting "browse" in the tables below.
