Suomi NPP VIIRS 11.45 \u00c2\u00b5m IR images<\/p><\/div>\n

A sequence of three AWIPS images of 1-km resolution Suomi NPP VIIRS 11.45 \u00c2\u00b5m IR data (above)<\/strong><\/em> showed the relatively compact cloud structure associated with Hurricane Henriette<\/strong><\/a> over the Eastern Pacific Ocean during the 07 August – 08 August 2013 period. Cloud-top IR brightness temperatures were as cold as -83 C (violet color enhancement)<\/em> on the 08 August\/11:12 UTC image. Henriette also exhibited a small eye on the 11:12 UTC and 22:26 UTC images on 08 August.<\/p>\n

On a night-time comparison of Suomi NPP VIIRS 0.7 \u00c2\u00b5m Day\/Night Band\u00c2\u00a0 and 11.45 \u00c2\u00b5m IR images at 11:15 UTC (below),<\/strong><\/em> it is interesting to point out that the eye could still be faintly identified on the Day\/Night Band image, even though there was only a minimal amount of illumination from airglow alone (the Moon was in its early Waxing Crescent phase, at only 1-3% of full, but was actually below the horizon<\/strong><\/a> for this particular image)<\/em>.<\/p>\n

The compact eye of Henriette was well-defined on a comparison of VIIRS 0.64 \u00c2\u00b5m visible channel and 11.45 \u00c2\u00b5m IR channel images at 22:26 UTC (below)<\/strong><\/em>. Henriette was near its maximum intensity of 90 knots around this time.<\/p>\n
