McIDAS images of GOES-13 0.63 \u00c2\u00b5m visible channel data (above; click image to play animation; also available as a QuickTime movie<\/a>)<\/em><\/strong> showed a number of convective bursts associated with the tropical storm — note that there were several periods where images were available at 1-minute intervals<\/em> while GOES-13 was in SRSO mode. The ABI instrument<\/a><\/strong> on GOES-R<\/a><\/strong> will actually be able to provide images as frequently as every 30 seconds<\/em> over special regions of interest (such as tropical cyclones or severe thunderstorms).<\/p>\n

A sequence of three AWIPS images of 1-km resolution MODIS and POES AVHRR IR data (below)<\/em><\/strong> displayed intricate cloud top structures and very cold cloud top IR brightness temperatures — as cold as -90\u00c2\u00baC<\/strong> (darker violet color enhancement)<\/em> on the 14:23 UTC MODIS image and the 20:21 UTC POES AVHRR image.<\/p>\n

\"MODIS<\/a>

MODIS 11.0 \u00c2\u00b5m and POES AVHRR 10.8 \u00c2\u00b5m IR images<\/p><\/div>\n

For the three individual 1-km resolution MODIS and POES AVHRR IR images above, comparisons with the corresponding 4-km resolution GOES-13 IR images are shown below. There are slight time differences between the MODIS\/AVHRR IR and the GOES-13 IR images — but the majority of the northwestward shift in the location of features on the GOES images is due to parallax<\/a><\/strong>.<\/p>\n

Even though the spatial resolution of the IR channels on the ABI instrument on GOES-R will be 2-km, these 1-km resolution comparisons still serve to demonstrate that improved spatial resolution should allow better detection of such detailed cloud top structures and cold cloud top IR brightness temperatures associated with tropical cyclones.<\/p>\n
