This product was developed using machine learning with satellite data (water vapor and infrared data) and Global Forecast System (GFS) meteorological variables as input, and is an improvement on a previous product that used only satellite data.  On 22 March, an important case of prevalent turbulence occurred across the North Pacific and the coast of Alaska.\u00a0 A training video on the product<a href=\"http:\/\/cimss.ssec.wisc.edu\/training\/TrainingVideos\/TurbulenceMLWimmers.mp4\"> is available here.<\/a><\/p>\n<p>The toggle above includes <a href=\"https:\/\/cimss.ssec.wisc.edu\/satellite-blog\/wp-content\/uploads\/sites\/5\/2021\/03\/G17Band08-20210322_131032.png\">GOES-17 Upper-Level Water Vapor infrared imagery<\/a> (6.19 \u00b5m) with and without <a href=\"https:\/\/cimss.ssec.wisc.edu\/satellite-blog\/wp-content\/uploads\/sites\/5\/2021\/03\/G17Band08_TurbReports-20210322_131032.png\">Pilot Reports of turbulence<\/a>, as well as <a href=\"https:\/\/cimss.ssec.wisc.edu\/satellite-blog\/wp-content\/uploads\/sites\/5\/2021\/03\/G17Band08_TurbReports_ISIG-20210322_131032.png\">ISIG turbulence polygons<\/a>.
