\"GOES-13<\/a>

4-km resolution GOES-13 6.5 \u00c2\u00b5m water vapor images<\/p><\/div>\n

15 April 2009<\/strong><\/a> was the last full day of GOES-13 imagery — the satellite was placed back into on-orbit storage on the morning of 16 April. GOES-13 had been brought out of storage during the Summer of 2008, to act as “GOES Central” (at 105\u00c2\u00ba West longitude)<\/em> and provide imagery through the Fall eclipse period. Larger on-board batteries allow GOES-13 to make imagery available during eclipse periods (when the satellite is in the Earth’s shadow, and the solar panels cannot provide the power necessary to operate the instruments)<\/em> –\u00c2\u00a0 but other improvements to GOES-13 include better image-to-image navigation, and the 4-km resolution water vapor channel that debuted on GOES-12.<\/p>\n

The 4-km resolution GOES-13 6.5 \u00c2\u00b5m water vapor imagery (above)<\/strong><\/em> displayed widespread mountain wave signatures across much of the western US on 15 April — and many of the smaller-scale areas of mountain waves were unable to be resolved using the 8-km resolution GOES-11 6.7 \u00c2\u00b5m water vapor imagery (below)<\/strong><\/em>.<\/p>\n

\"8-km<\/a>

Such mountain wave signatures are often a good indicator of the likelihood of turbulence — and there were indeed a large number of pilot reports (PIREPS) of turbulence (including at least 11 reports of severe turbulence<\/strong>)<\/em> across much of the western US, as seen on AWIPS images of the GOES-11\/GOES-12 water vapor channel data (below<\/strong><\/em>).<\/p>\n

AWIPS images of the 1-km resolution MODIS 6.7 \u00c2\u00b5m water vapor channel data (below)<\/strong><\/em> displayed even better mountain wave details at 18:46 and 20:31 UTC.<\/p>\n
