Data from these satellites is transmitted to Earth and used to construct a. Morgan Rehnberg ( Science Writer Citation: Rehnberg, M. NASA has satellites orbiting the Earth with sensors designed to detect lightning. ( Journal of Geophysical Research: Atmospheres,, 2023) These novel capabilities, the authors say, expand the horizon of what’s possible in the study of lightning physics. They even demonstrated that for events with linear polarization, BIMAP-3D can deduce the orientation of the radio polarization in three dimensions. They computed 3D maps showing the shape and development of each lightning event, including both cloud-to-cloud and cloud-to-ground events. The team then applied their new instrumentation and analysis techniques to several observed lightning strikes. What’s more, they could track the development of lightning within fractions of a microsecond. Under favorable conditions, the researchers could pinpoint a lightning strike’s source location to within several meters at an altitude of kilometers aboveground. They can integrate these two analyses for accurate triangulation. The authors describe two techniques for triangulating the path of a lightning strike by combining data from the two stations: one based on geometry and the other based on time of arrival. By using both stations simultaneously, scientists can map lightning and detect polarization in three dimensions. These stations, which are separated by 11.5 kilometers, each consist of four sets of broadband and polarized antennas arranged in a Y shape. Their second-generation BIMAP-3D (Broadband Interferometric Mapping and Polarization in 3D) system utilizes two observation stations. Adding a third dimension could resolve these long-standing problems in lightning physics. extended radio-frequency interferometry and polarization detection to three dimensions. When using a map, you should refer to and contributors for the lightning data in the map and refer to for the map itself. bietet aktuelle Informationen über Blitze und Gewitter in Echtzeit live auf verschiedenen Karten für Deutschland, Österreich und die Schweiz.
