A Himawari-8 “Target Sector” was positioned over that region — providing rapid-scan (2.5-minute interval)<\/em> imagery — as seen in a 2-panel comparison of AHI<\/strong><\/a> Visible (0.64 \u00b5m) and Infrared Window (10.4 \u00b5m) data covering the first 7 hours of the eruption (above)<\/strong><\/em>. Ash plume infrared brightness temperatures quickly became -40\u00baC and colder (bright green enhancement)<\/em>.<\/p>\n Himarari-8 false-color RGB images [Click to play animation]<\/p><\/div>Himawari-8 false-color Red\/Green\/Blue (RGB) images from the NOAA\/CIMSS Volcanic Cloud Monitoring<\/strong><\/a> site (above)<\/strong><\/em> showed the ash plume drifting south-southwestward during the subsequent nighttime hours. It is interesting to note the formation and subsequent northwestward motion of numerous contrails (darker<\/em> green linear features)<\/em> across the region, due to the close proximity of a major Tokyo flight corridor.<\/p>\n True-color RGB images from Terra MODIS, Suomi NPP VIIRS and Aqua MODIS, viewed using RealEarth<\/strong><\/a> (below)<\/strong><\/em> revealed the long ash plume during the late morning and early afternoon on 25 March. The dark signature of ash fall onto the snow-covered terrain was evident on the Terra and Aqua images, just west of the high-altitude ash plume.<\/p>\n<\/a>
