![]() (2) The 1-minute mean data is calculated within our archive using the search feature below or by submitting a “Data Request.” See the “Help” section for an important explanation about how the 1-minute mean is calculated. It is available under the “Raw Historical Data,” along with the executable file needed to extract the data and output it in ASCII format. Over 800 million cloud to ground lightning flashes were observed between 19 across the Continental US. Thats more than a hundred lightning bolts. The LPLWS data is available in two forms: (1) The 50 Hertz (Hz) data is the raw electric potential gradient data. Every year, the Earth experiences an average of 25 million lightning strikes during some 100,000 thunderstorms. The merged lightening & satellite cloud top temperature operational product is a joint. provides lightning and thunderstorm information in real-time on maps for USA, United Kingdom, Australia, new Zealand, Europa, Africa. In most cases, E will be large close to the cloud charges and small farther away, so 2-dimensional maps of E will show approximately where the cloud charges are located. Lightning India Contour Lightning India Contour. When an electrified cloud forms overhead or moves into the region, the E field will increase and often change polarity. The amplitude and polarity of the current flowing to and from the stators is proportional to the amplitude and polarity of the local electric field. The sensors are termed ‘mills’ because they employ a rotating and grounded metallic shutter to alternately cover and uncover a set of insulated stators that respond to E. ![]() The Launch Pad Lightning Warning System (LPLWS) is a large-area network of 31 electrostatic field sensors (field mills) that measures the vertical component of the electrostatic field, E, produced by cloud charges aloft, even if those clouds are not producing lightning. ![]()
