About this dataset

The colors on this collection of daily global maps show where the land and ocean was covered by snow (gray and white) and ice (blue). If you browse through these maps you will notice that snow and ice cover Earth's polar regions with bright white caps all year round. But at lower latitudes the extent of snow and sea ice changes as the seasons change. Scientists measure how much of our world is covered by snow and ice to help them better understand and predict changes in Earth's weather and climate.

What do the colors mean?

The dark- to light-blue colors indicate the percentage of sea ice cover for the given time period. Light gray areas show dry snow extent over land. White areas show the permanent ice sheets on Greenland and Antarctica. Black indicates where there is no data.

Notes

Issues related to data production resulted in no data being ingested for this dataset from May 8, 2009 to January 3, 2010.
