An intense winter storm impacted a large portion of the mid-Atlantic and Northeast regions of the US on 18 December<\/a> – 19 December 2009<\/a><\/strong>, creating blizzard conditions and setting a number of snowfall records (listing of snowfall totals<\/a><\/strong>). As a part of its ongoing NOAA Science Test<\/a><\/strong>, the GOES-14 satellite was placed into Super Rapid Scan Operations (SRSO) mode, supplying imagery at 1-minute intervals during much of the storm life cycle. McIDAS images of the GOES-14 10.7 \u00c2\u00b5m IR channel data (above; <\/strong> click image for a 61 MB QuickTime animation)<\/em><\/strong> showed the formation of a large, cold cloud shield early in the period, followed by the development of a number of convective bands after about 03:00 UTC on 19 December which then helped to further enhance snowfall rates.<\/p>\n

As the storm center was moving across the northern Gulf of Mexico on 18 December, it even exhibited an eye-like appearance on GOES-14 visible channel images (below; <\/strong>click image for a QuickTime animation)<\/em><\/strong>, which is suggestive of a warm seclusion<\/a><\/strong>. <\/p>\n

On 19 December, a comparison of 15-minute interval GOES-12 and 1-minute interval GOES-14 visible images centered off the east coast of the Delmarva Peninsula (below; courtesy of Tim Schmit, NOAA\/ASPB)<\/em><\/strong> offers a compelling demonstration of the value of more frequent imaging for monitoring the development and evolution of cloud features. During this 18:15 – 19:04 UTC time period, there were only 3 images available from GOES-12, compared to 44 images using GOES-14. A longer animation of GOES-14 SRSO visible imagery during the afternoon hours on 19 December can be seen here<\/a><\/strong>.<\/p>\n

On the day following the storm (20 December), a comparison of AWIPS images of the MODIS visible channel and a false-color Red\/Green\/Blue (RGB) image (below)<\/em><\/strong> demonstrates the value of using RGB imagery to help discriminate between snow cover (red-enhanced features)<\/em> and supercooled water droplet clouds (brighter white features)<\/em> across the mid-Atlantic states. This also offers a glimpse at the type of RGB image capability that should be available with the upcoming AWIPS-2 software.<\/p>\n
