The strength of the 1.375 \u00b5m spectral band is the detection of particles that are efficient scatterers of light (such as cirrus ice crystals, volcanic ash, haze, and dust)<\/em> — so in this case the dense plumes of blowing dust showed up very well, especially in comparison to the corresponding visible image. Note that a 1.38 \u00b5m “Cirrus” band<\/strong> will be available with the ABI<\/strong><\/a> instrument on the upcoming GOES-R<\/strong><\/a> satellite.<\/p>\n
