Lightning energy during the HWT was introduced in several different ways. Three of these were:<\/p>\n

 <\/p>\n

    \n
  1. Flash Extent Density<\/li>\n
  2. Minimum Flash Area<\/li>\n
  3. Total Optical Energy<\/li>\n<\/ol>\n

     <\/p>\n

    For monitoring severe thunderstorms, Flash Extent Density seemed to be the most useful of the three.<\/p>\n

    However, all of the GLM products were what we focused on.<\/p>\n

    In order to obtain GLM lightning data on the grid or map, you had to obtain a Minimum Flash Area. It was interesting in the stratiform type storms that a wide area was displayed compared to the small area where the flash took place. In this case it was one cloud-to-ground lightning strike (CG).<\/p>\n

    This is the top-right panel (Minimum Flash Area):<\/p>\n

    \"\"<\/p>\n

    This shows that one CG Flash can plot a large area on the Minimum Flash Area product. It seemed that this was necessary for other products to plot, such as the Flash Extent Density, but it may be a little bit of a distraction for the operational forecaster as it would seem to flash a bit (on and off if looping it) and for a much larger area than what was shown compared to the cloud Flash and CG plots.<\/p>\n
