First official GOES-15 10.7 \u00c2\u00b5m longwave IR image (click image to enlarge)<\/p><\/div>\n

The first official GOES-15 full disk InfraRed<\/strong> (IR)<\/strong> images became available at 17:30 UTC on 26 April 2010<\/a><\/strong>. The GOES-15 Imager 10.7 \u00c2\u00b5m longwave IR image is shown above – similar images are available for the 0.65 \u00c2\u00b5m visible channel<\/strong><\/a>, the 3.9 \u00c2\u00b5m shortwave IR<\/a><\/strong>, the 6.5 \u00c2\u00b5m water vapor channel<\/a><\/strong>, and the 13.3 \u00c2\u00b5m CO2 channel<\/a><\/strong>.<\/p>\n

GOES-15 was launched on 04 March 2010, with the first visible images<\/a><\/strong><\/a> from the Imager<\/a><\/strong> instrument available on 06 April and from the first visible images<\/a><\/strong> from the Sounder<\/a><\/strong> instrument on 08 April. GOES-15 will have a Post Launch Test<\/strong><\/a> beginning in August 2010.<\/p>\n

Some close-up comparisons of GOES-13 and GOES-15 IR images show similar results from the two satellites. The image above uses GOES-13 and GOES-15 10.7 \u00c2\u00b5m longwave IR channel data to display a cluster of strong convection over the far eastern Gulf of Mexico, between Florida and Cuba — the coldest 10.7 \u00c2\u00b5m IR brightness temperatures seen were 196.2 K (-77.0\u00c2\u00ba C)<\/strong> on GOES-13, vs 194.9 K (-78.3\u00c2\u00ba C)<\/strong> on GOES-15. <\/p>\n

The image below is a comparison of the 13.3 \u00c2\u00b5m CO2 channels. Note that the Field of View (FOV) of the 13.3 \u00c2\u00b5m CO2 channel has improved from 8 km<\/strong> on GOES-13 to 4 km<\/strong> on GOES-15 — as a result, the edges of cloud features now appear much smoother on the GOES-15 13.3 \u00c2\u00b5m image.<\/p>\n

Looking farther to the west, the image below shows the Gulf of Mexico Loop Current<\/strong><\/a>, using the 3.9 \u00c2\u00b5m shortwave IR channel data from GOES-13 and GOES-15. AWIPS images of the Sea Surface Temperature (SST) products from MODIS<\/strong><\/a> and AVHRR<\/strong><\/a> indicated that the SST values were as warm as 80\u00c2\u00ba F within the Loop Current, surrounded by waters with SST values in the 70-75\u00c2\u00ba F range.<\/p>\n

A comparison of the GOES-13 and GOES-15 6.5 \u00c2\u00b5m water vapor channels (above)<\/strong><\/em> showed a pocket of very dry air (yellow to orange color enhancement)<\/em> to the north of the aforementioned strong convection located between Florida and Cuba. This dry air was a signature of a well-defined\u00c2\u00a0 “jet stream break”, as verified by GFS model 250 hPa wind speed isotachs (below)<\/strong><\/em>.<\/p>\n
