GLM 1-min vs 5-min Accumulation

For most of the week, the products from GLM were 1-minute updating every 1-minute. For this user, it was difficult to identify relevant trends in the fields (rapid increases or decreases), or to connect lightning cores with their appropriate storms as seen in radar imagery. Today, the products were converted to 5-minute accumulation (updating every 1-minute) about midway through the shift, allowing for a comparison between the two methods. See below. The 5-min accumulation updating every 1-minute, in my opinion, allows for much easier identification of significant trends, as well as tracking of lightning cores and relating lightning features to radar imagery.

The animation below includes 1-min visible imagery with 1-min GLM Flash Extent Density overlaid. The loop begins with the 1-min product, and transitions to the 5-min accumulation product updating every 1-minute.
