Eastern Great Lakes ice analysis

(13-15 February 2001)

NOAA GOES-8 visible channel imagery (above, left) shows a large region of ice covering much of the eastern portion of Lake Erie on 12 February 2001. Large fissures are evident in the ice structure. A National Ice Center lake ice analysis (above, right) shows that this part of Lake Erie had 9 to 10 tenths of ice coverage. There is greater ice coverage on Lake Erie compared to the adjacent Lakes Ontario and Huron due to the fact that the water is more shallow in Lake Erie, allowing the water temperatures to cool and freeze more quickly in winter. GOES imagery documenting the evolution of Lake Erie ice cover during the 2000-2001 season are available from the Buffalo NY National Weather Service office.

Higher resolution visible channel imagery from the NASA Terra MODIS instrument (below) reveals even greater detail in the lake ice and fissure structure. Recent examples of MODIS visible imagery are available from the NASA Goddard MODIS Direct Broadcast site.
