Number of Frames:
When making a loop, the initial render time will be slower while
the server generates the images. However, subsequent "Update Plot"
requests should be fast since existing frames in the animation will
not need to be regenerated.

GOES Geostationary Lightning Mapper (GLM): 4 products available:
1) GOES 16 flashes (lat/lon points of flash centroids; 10 min sum)
2) GOES 17 flashes (lat/lon points of flash centroids; 10 min sum)
3) Flash extent density (units: flashes/grid box/10-min): Description
4) Total optical energy (units: 10-15J): Description

ASCAT details: Passes within 6 hours of the satellite image will be
displayed (if set to "On" in the Display Settings menu in the lower-
left portion of this page). On color-enhanced images, red barbs
indicate locations where the ASCAT quality flags were non-zero
meaning there could be errors in speed or direction at these locations.

Don't forget to try out the Measure tool in the left column to see
how far a feature is from your point of interest! (non-loop mode only)
