However, a comprehensive national summary of seasonal, monthly, and weekly lightning across the contiguous United States has not been developed. The Meteorological Institute is responsible for the sensor network for lightning observations in Norway. Annual maps of cloud-to-ground lightning flash density have been produced since the deployment of the National Lightning Detection Network (NLDN). The accuracy of the observations is around 200 metres. The more sensordata, the more reliable is the calculated position for the lightning discharge. Here, packets from all the sensors are sorted, and those that belong together from the same discharge, are then grouped together. Time, direction and some other information about the lightning discharges are collected as a package of information which is sent to the Meteorological Institute's systems. A lightning discharge has a "signature" that allows the sensor's software to distinguish lightning discharges from all the other electrical noise in the world. The sensors are basically a bearing antenna with a very accurate clock and a computer. The observations are measured with the help of a network of sensors. The map shows both lightning from cloud to cloud and from cloud to ground.Ī lightning observation is a positioned discharge that is registered and calculated from two or more sensors. The most recent lightning observations are animated and orange, older observations are shown on the map with two shades of purple (1-60 minutes) and two shades of gray (1-24 hours). You can view lightning observations seconds after they are recorded and up to 24 hours back in time. The system enables fire managers to monitor cloud-to-ground lightning activity on a. The lightning map shows near real-time lightning observations in Norway, Sweden, Denmark and Finland. Alberta Wildfire operates a lightning detection system developed by VAISALA. In some cases, it can also mean that what is marked as beta is not as stable as other things on the service, and that there is a somewhat greater probability that errors may occur. We do this mainly when we believe that something has value for the users even in an unfinished state, and because we want feedback on something we are working on. A beta label on Yr means that we launch something on the service before it is completed.
