\"GOES-11,<\/a>

GOES-11, GOES-12, and GOES-14 visible images<\/p><\/div>\n

GOES-14 (launched on 27 June 2009)<\/em> began its NOAA Science Test<\/a><\/strong> on 30 November 2009<\/a><\/strong> — and McIDAS images of the GOES-11, GOES-12, and GOES-14 visible channel data (above)<\/em><\/strong> showed an area of melting snow cover across the Texas \/ New Mexico border region. This area (southwest of Amarillo, Texas)<\/em> had received 1-3 inches of new snowfall<\/a><\/strong> on 29 November, which then rapidly melted under full sun on the following day. Note the improvement in Image Navigation and Registration (INR) on the GOES-14 images — there is much less image-to-image wobble compared to the GOES-11 (GOES West)<\/em> and GOES-12 (GOES East)<\/em> images. The 3 sets of images are displayed in the native projection of their respective satellites.<\/p>\n

Better INR performance is critical to improving the accuracy of such satellite-derived products as the 1-hourly MADIS atmospheric motion vectors, seen overlaid on an AWIPS image of the MODIS 11.0 \u00c2\u00b5m IR channel data (below)<\/em><\/strong>.<\/p>\n

A comparison of the MODIS visible and 2.1 \u00c2\u00b5m near-IR “snow\/ice channel” images (below)<\/em><\/strong> confirms that this feature was indeed snow — snow and ice are strong absorbers at the 2.1 \u00c2\u00b5m wavelength, and appear as very dark<\/strong> features on the snow\/ice image.<\/p>\n

Note how the MODIS Land Surface Temperature (LST) product (below)<\/em><\/strong> was showing LST values in the upper 30s to low 40s F (green colors)<\/em> over the snow-covered areas, in contrast to much warmer LST values in the middle 50s to low 60s F (yellow colors)<\/em> over the surrounding bare ground. The surface air temperatures were also being held down into the upper 30s to low 40s F over the melting snow cover.<\/p>\n
