LiDAR can build an exact replica of a 3D image of the object: LiDAR technology is used to recreate an exact replica of the object being detected and measured in 3D images. The data returned will be independent of each object on the surface. Hail is a good reflector of energy and will return very high dBZ values. LiDAR sensors can detect even the smallest of objects from the surfaces because of the short wavelength. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Depending on the type of weather occurring and the area of the U.S., forecasters use a set of rainrates which are associated to the dBZ values. The higher the dBZ, the stronger the rainrate. Typically, light rain is occurring when the dBZ value reaches 20. Your best resource for Local Peoria, Arizona Radar. The scale of dBZ values is also related to the intensity of rainfall. Peoria, AZ Doppler Radar Weather - Find local 85345 Peoria, Arizona radar loop and radar weather images. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Notice the color on each scale remains the same in both operational modes, only the values change. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). "Reflectivity" is the amount of transmitted power returned to the radar receiver. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. ![]()
