Original Ice Charts

Ice Charts | Period of Record Files


Documentation: Original Ice Charts [pdf]

A total of 1210 ice charts are available in ARC/INFO export format and as formatted ASCII Grids. These data are arranged by winter season from 1973 through 2002.

Each winter season contains three types of files:
1) Graphic files of total ice concentration
2) ARC/INFO export files (in Zip compression)
3) ASCII Grid files (in Zip compression)

In addition, ASCII grids for a 28-year Period of Record (POR), 1973 through 2000, can be downloaded (in 15 Zip compression files), one file for each of the 15 ice attributes listed on the POR link. These data were generated in an earlier study.
