Information
The figures are generated every hour. The inputs row lets you change images for each fire, date, and hour. You change the images by hovering your mouse over the buttons.
Hover Button Rows
- Images from GOES-16 for the hour selected. There are images every 5 minutes. The image is a blended "TrueColor" and "FireTemperature" product, with GLM lightning data showing flashes indicated by small yellow crosshairs. Be aware of "parallax" which makes tall clouds appear larger and lightning point data to appear skewed. The GLM data is parallax corrected with an assumed cloud height.
- Lightning data from the Geostationary Lightning Mapper: note,
the lightning mapper "measures" total lightning
(intracloud+cloud-to-ground) simply by identifying "bright"
regions in the near IR channel and interprets those flashes as
lightning. You will notice some parallax in the GOES-16 images
(flash are shifted slightly south of the cloud's convective
center) which I haven't solved yet. The idea with these plots
is to show where the lightning has been observed and how it has
moved in the last 90 minutes.
GLM Documentation.
- GLM_map - map centered on fire start location, a 300 mile radius is shown in red, and the accumulated flashes for the previous 0-30 minutes (black), 30-60 minutes (grey), and 60-90 minutes (white). The HRRR 500 mb wind barbs are plotted using HRRR data from that hour.
- GLM_histogram - a histogram describing the distance of the flashes relative to the fire.
- GLM_proximity - a scatter plot showing flashes by distance and direction from the fire.
- GLM_rose30 - a "lightning rose" showing how many flashes are in each direction and how close they are relative to the fire for the previous 0-30 minutes. The length of a rose petal is the count of lighting flashes in that direction. The color represents the relative distance from the fire where yellow is closer to the fire than purple.
- GLM_rose60 - same as GLM_rose30, except showing lightning for previous 30-60 minutes.
- GLM_rose90 - same, but for previous 60-90 minutes.
- HRRR point-forecast initialized at the hour. Forecast image for each 18 forecast hours.
- HRRR forecast hovmoller to show how HRRR forecasts have changed.
