The National Snow and Ice Data Center (NSIDC) has released new
animations for Google Earth showing daily arctic sea ice concentrations
and daily arctic sea ice extent for the most recent 30, 60, or 90 days.
Images are derived from The Near Real-Time SSM/I EASE-Grid Daily Global
Ice Concentration and Snow Extent (NISE) product, which has been
produced at NSIDC on a daily basis for the past decade.
Monthly average sea ice extents are also shown to give an indication of
how current conditions compare with more typical conditions.
The daily updates are automatically loaded into Google Earth at startup
so users always have the most recent images. Users with limited memory
or bandwidth may want to choose a shorter time series.
The 30-, 60-, and 90-day kml files are available from the NSIDC virtual
globes home page. To view these images, please go to:
