Bundesland Radar-Standorte wechseln Standortauswahl ausblenden. Our neighboring radars (Chicago, Davenport, St. Louis, Evansville, Indianapolis) will be available for use if necessary an MTI radar or a pulse Doppler radar. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Typically, light rain is occurring when the dBZ value reaches 20. Lincoln ne radar loop weather copyright © Prof. Dr. Md. Simulated radar displayed over oceans, Central and South American countries is generated from satellite data, which is provided up to the current time and may not be updated as frequently as other regions.
