Here's another comparison of GLM flash extent density with ENI flashes and pulses. GLM parallax displacement is again apparent with the line of storms extending southwestward across western SD into eastern WY. Allowing for that, there is good general agreement between the two data sources regarding lightning location and concentration. The GLM FED clearly gives a more complete picture of the area extent of lightning.
The next image shows GLM flash centroid density (blue boxes) instead of FED. Most of the values are 1 indicating a single flash centroid. (This product is probably not destined for operations.) Interestingly, these GLM flash centroids match up fairly well with the ENI flashes and also with the MRMS RALA reflectivity cores. A.Cope
