The default color scale for gridded lightning data is not very useful…as it goes all the way to 30,000 flashes. This is pretty unreasonable even for the most electrically active storm. Shown here is the 5 min total lightning data for the ENTLN gridded data at 8 km, 5 km, 3 km, and 1 km using the default color scale (with 30000 as the upper limit) and another image showing a more reasonable color scale (with 300 as the upper limit). Clearly, analysis is far easier using the adjusted color scale as the finer scale details are much easier to see. I also find that interpolating the gridded data makes visualization far easier.
