Description:
A 28-winter digital ice cover data set consisting of 1122 ice charts was established for the Great Lakes. Data reduction and quality control procedures are described in Norton et al. (2000). The data are available in ARC/INFO export and ASCII grid formats. Three types of ice attribute data are given: ice concentration class (the fraction of a unit of surface area covered by ice), ice stage class (range of ice thicknesses), and ice form class (size of ice floes). Ice attribute data coding conventions are described and discussed. The temporal and spatial distribution of the ice chart dates and ice attribute data are summarized in a table and in graphs. Metadata is provided as appendices.
