Statistical Lightning Products
Historical lightning data can be transformed into valuable statistical derivations such as lightning density maps and area cloud-to-ground stroke counts.Lightning Density Maps
Lightning Density Maps graphically depict the areas of highest and lowest lightning concentration by contouring the number of lightning events within a given area and time. Lightning Density Maps can be generated for any spatial or temporal coverage available within the USPLN, and for just cloud-to-ground strokes or inclusive of cloud lightning events. Seasonal and regional maps are ideal for defining areas of lightning activity for operational, safety, and equipment management.
The 5-Year Average Lightning Density Map for the continental United States is shown below. This map has been generated using a 0.1 degree pixel (approximately 10km).
Comparisons of annual Lightning Density Maps and their underlying detailed data provide additional tools for understanding failures and outages, planning and optimizing asset deployment and land usage, and targeting operational, personnel and equipment safety.
Area Stroke Counts
Cloud-to-ground stroke counts per state per year provide useful complementary information to the stroke density maps. Data from 2005 can be regionally summarized for territory analysis of lightning activity.
A summary of 2009 data along with state rankings since the inception of the network can be downloaded below.
