The grided GLM data appears to be reliable near the nadir, but issues appear when you move farther to the edges of the GOES-16 domain. The below image is from New Jersey, this afternoon. The individual boxes or plots for events as you go clockwise around the image, 5km, 8km, 10km, 9km, resolutions, remain the same as they should. However, the grid that is derived for each resolution does not change with grid projection of GOES-16, they remain uniform. This results in individual events being counted twice in one grid box or data drop outs. you can see examples of both as you look at the different projections. The grid resolution should mimic that of the GOES-16 grid resolution, which is dependent on the distance/location from its nadir.
