GOES-16 Level 2 Sea Surface Temperature product with Default Enhancement, re-scaled enhancement, and re-scaled enhancement with GOES-16 ABI 0.64\u00a0\u00b5m visible imagery, 1502 UTC on 19 March 2018 (Click to enlarge)<\/p><\/div>\n

One of the Level-2 products in AWIPS is Sea-Surface Temperature.\u00a0 This is created hourly on the Full Disk scale, and is shown above.\u00a0\u00a0 The image above toggles between the default enhancement<\/a> (from -5\u00ba to 40\u00ba Celsius) to one that is more appropriate for mid-March<\/a> (-5\u00ba to 30\u00ba Celsius), and then with the ABI Band 2 (0.64 \u00b5m) Visible Image<\/a>.\u00a0 This allow change allows for features in the Gulf of Mexico to become more obvious. (Note: The default Sea-Surface Temperature enhancement in AWIPS will change in the future; the maximum value will be 35\u00ba C, not 40\u00ba).<\/p>\n

Sea-Surface temperatures over the Great Lakes, under clear skies, are not displayed. Sea-Surface temperatures are currently computed only over the oceans — not over large lakes.<\/p>\n

GOES-16 Land Surface Temperature, computed hourly in the CONUS domain, does include Great Lakes water temperatures; it is shown below<\/a> (Here is it in a toggle with different ABI Channels<\/a>). The default temperature scale for Land Surface Temperature is -10\u00ba to 110\u00ba (Fahrenheit), which is different than the default for Sea-Surface Temperatures. The cold mid-March temperatures (low to mid-30s, generally, with a few sub-30s showing over ice) of the Great Lakes stand out plainly. Regions of ice do persist over the Great Lakes, as is apparent in this toggle<\/a> between ABI’s Visible<\/a> (Band 2, 0.64 \u00b5m), Snow\/Ice Near-Infrared<\/a> (Band 5, 1.61 \u00b5m) and Cirrus Near-Infrared<\/a> (Band 4, 1.37 \u00b5m) Imagery at 1502 UTC.\u00a0\u00a0\u00a0 Lake ice remains over eastern Lake Erie, eastern and northern Lake Superior, and north of Manitoulin Island<\/a> in Lake Huron.<\/p>\n
