In polar regions, near real-time (NRT) Moderate Resolution Imaging Spectroradiometer (MODIS) images provided by NASA's Land, Atmosphere Near real-time Capability for EOS (LANCE) are routinely used by the Polar Geospatial Center, in combination with other data, to provide up to date information on ice conditions to ships and research vessels.
Potentially useful data sets: MODIS Corrected Reflectance True Color and Bands 3-6-7, MODIS Sea Ice, Brightness Temperature (Band 31 day and night)
By combining information from MODIS Bands 3-6-7, it is possible to differentiate sea ice from clouds. Red shades indicate ice, while tan and white shades indicate clouds. Such information can be used in conjunction with other data, to provide ships in the Antarctic with up-to-date information on sea ice conditions which are used to help ships safely plot their course through icy waters.
