MODIS (Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the NASA Terra and Aqua satellites. The Terra and Aqua MODIS instruments view the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands at resolutions of up to 250 m. The image is a composite of bands 1, 4, and 3, a true color picture of the Bering Strait from the 22nd of May 2002.
