The PGLM used total lightning data from three Lightning Mapping Array (LMA) networks including the Oklahoma Lightning Mapping Array (OKLMA) and the Lightning Detection and Ranging network that detects radio waves emitted in the very high frequency range by lightning flashes. LMA systems also detect radio noise, but in the very high frequency (VHF) band around 60 MHz. Since there are many other sources of radio noise, the systems have to first identify which bursts are likely to be caused by lightning. Glossary Short Range Forecast Amazon Web Services offsite linkGoogle offsite link Review the documentation to learn about FTP access options. CG flashes that bring negative charge from the cloud to ground (negative CG or -CG) can have multiple return strokes, which can sometimes be seen visually as a flickering of the channel to ground. Rivers Most ground-based observations in the 3 - 30 kHz VLF band are dominated by impulsive signals from lightning discharges called "sferics". Step 1: Report Information . NDLN provides a wealth of significant lighting data on individual strikes including cloud-to-ground stroke or in-cloud pulse designation, location, duration polarity, and peak current.
