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. The scale of dBZ values is also related to the intensity of rainfall. 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. Optional satellite/cellular data service seamless backup, for those times when severe weather takes out communications.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.Exclusive hot-button hardware control panel and programmable clicker gives you “at a touch” preset views for “Live at the Weather Center” cameos.Touch-screen interactivity is built in, use ours, or your own on-set touch screen for live weather events.4 button programmable clicker gives you “at a touch” preset views while in chroma-key.Combined with a custom time slider bar, users can adjust map time down to the minute. Virtually all of XRAD3D’s data products can use our signature “time interpolation” feature which smoothly animates and displays interstitial frame values on the unified program timeline.Complete weather model and weather data support for overlay at the synoptic level and mesoanalysis level.Built-in street level mapping, road sign labeling, and standard GIS layers give viewers a crystal clear sense of weather and geographical space. XRAD3D features a dynamic 3D GIS world model mapping system and is one of only a few in the world to ingest and style ESRI Shapefile data at the user’s configuration and display it with hardware-accelerated, fluid graphics – delivering precise weather graphics animations on consumer graphics hardware.Advanced storm-cell tracking features with ETA arrival times.XRAD3D features an advanced super-resolution 0.5km x 0.5° grid of highly practical derived products such as estimated hail size (MEHS), Wind Shear/Rotation, Echo Tops (ET), thunderstorm gusts, severe hail probabilities (POSH), and more.You will find this capability nowhere else.
