4 km 3-Color Vis/SW/IR -

This product is a Red-Green-Blue (RGB) combination of three images. The Red color is used to display the Visible Albedo product; the Green color is used to display the Shortwave Albedo product; and the Blue color is used to display the IR window band (10.7 µm). The Visible Albedo is the solar-zenith-angle-corrected visible (0.7 µm) radiance, corrected to appear as if the sun is overhead at all locations. The Shortwave Albedo is the reflected component only of the Shortwave (3.9 µm) radiance, which is also solar-zenith-angle-corrected to appear as if the sun is overhead at all locations. This product shows non-snow-covered land surfaces as either gray/green, low/water clouds as white, and high/ice clouds as magenta. Snow-covered land surfaces are a different shade of magenta. Also, because of the shortwave band, hot spots from fires may appear in the cloud free areas. This product changes at night when the visible and reflected component of the shortwave bands change characteristics, so it is most useful during the day.
