The following links can help you visualize MODIS data:


This application allows you to interactively browse global satellite imagery within hours of it being acquired. You can also save it, share it, and download the underlying data.

NSIDC Data on Virtual Globes: Google Earth

NSIDC developed a new .kml file providing monthly average snow cover, each month for one year. The snow cover data are derived from the MODIS/Terra Snow Cover Monthly L3 Global 0.05Deg CMG (MOD10CM), Version 5 data set. Each year of monthly snow cover is stored in a separate file; an additional file is provided with the most recent rolling 12 months of data. Data are available from 2000 to the most recent year. Coverage is global. The monthly snow cover images can be animated using the Google Earth time tool.

MODIS Mosaic of Antarctica (MOA)

MOA provides a cloud-free view of the ice sheet, ice shelves, and land surfaces at a grid scale of 125 m and an estimated resolution of 150 m. All land areas south of 60°S that are larger than a few hundred meters are included in the mosaic. Also included are several persistent fast ice areas and grounded icebergs. MOA consists of two MODIS-derived image data sets: a digitally smoothed red-light image, which was compiled using Band 1; and a snow-grain-size image, which was compiled using the normalized difference of calibrated data from Band 1 and Band 2 data.
