Lightning Mapping Array systems provide a fully three-dimensional picture of the storm

Lightning Mapping Array systems provide a fully three-dimensional picture of the storm
Lightning Mapping Array has proven to be very useful in the analysis of cloud charge structure
- •
The analysis suggests that strong cloud signals are misclassified as negative cloud-to-ground discharges
- •
Misidentification results in an excessive number of negative CG, which cover up the positive CG predominance
- •
The presence of regions with an inverted charge structure during some phases of the storm favors positive CG
